1 00:00:03,710 --> 00:00:01,850 Michael Levin's work on regulating 2 00:00:05,329 --> 00:00:03,720 intractable pattern formation in living 3 00:00:07,610 --> 00:00:05,339 systems has made him one of the most 4 00:00:09,169 --> 00:00:07,620 compelling biologists of our time in 5 00:00:10,549 --> 00:00:09,179 Translation this means that his team is 6 00:00:12,530 --> 00:00:10,559 sussing out how to develop limbs 7 00:00:14,629 --> 00:00:12,540 regenerate limbs how to generate minds 8 00:00:16,730 --> 00:00:14,639 and even life extension by manipulating 9 00:00:18,410 --> 00:00:16,740 electric signals rather than genetics or 10 00:00:20,090 --> 00:00:18,420 epigenetics his work is something that I 11 00:00:21,109 --> 00:00:20,100 consider to be worthy of a Nobel Prize 12 00:00:23,150 --> 00:00:21,119 and I don't think I've said that about 13 00:00:24,950 --> 00:00:23,160 anyone on the podcast Michael Levin's 14 00:00:26,509 --> 00:00:24,960 previous podcast on toe is in the 15 00:00:28,070 --> 00:00:26,519 description that's a solo episode with 16 00:00:30,170 --> 00:00:28,080 him where we go into a two-hour Deep 17 00:00:31,910 --> 00:00:30,180 dive as well as there's a Theo locution 18 00:00:34,010 --> 00:00:31,920 so that is him and another guest just 19 00:00:35,510 --> 00:00:34,020 like today except between Carl friston 20 00:00:37,610 --> 00:00:35,520 and Chris fields on Consciousness 21 00:00:39,590 --> 00:00:37,620 yoshibak is widely considered to be the 22 00:00:41,569 --> 00:00:39,600 Pinnacle of an AI researcher dealing 23 00:00:44,150 --> 00:00:41,579 with emotion modeling and multi-agent 24 00:00:46,190 --> 00:00:44,160 systems a large focus of boxes to build 25 00:00:48,049 --> 00:00:46,200 a model of the Mind from strong AI 26 00:00:50,029 --> 00:00:48,059 speaking of Mind Bach is one of the most 27 00:00:51,950 --> 00:00:50,039 inventive Minds in the field of computer 28 00:00:53,750 --> 00:00:51,960 science and has appeared several times 29 00:00:55,610 --> 00:00:53,760 on toll prior again there's a solo 30 00:00:57,470 --> 00:00:55,620 episode there's also a theologution 31 00:00:59,090 --> 00:00:57,480 between yoshibak and Donald Hoffman on 32 00:01:01,970 --> 00:00:59,100 Consciousness and yo shabach and John 33 00:01:03,830 --> 00:01:01,980 vervaki also on in reality biology has 34 00:01:05,690 --> 00:01:03,840 much to teach us about artificial 35 00:01:07,310 --> 00:01:05,700 intelligence and vice versa this 36 00:01:08,570 --> 00:01:07,320 discussion between two brilliant 37 00:01:09,710 --> 00:01:08,580 researchers is something that I'm 38 00:01:12,170 --> 00:01:09,720 extremely 39 00:01:14,570 --> 00:01:12,180 lucky blessed fortunate to be a part of 40 00:01:15,830 --> 00:01:14,580 as well as us as collective as an 41 00:01:17,570 --> 00:01:15,840 audience that are fortunate enough to 42 00:01:19,730 --> 00:01:17,580 witness approximately 30 minutes into 43 00:01:22,310 --> 00:01:19,740 the conversation you'll see two sponsors 44 00:01:24,410 --> 00:01:22,320 they are Masterworks and Roman I implore 45 00:01:26,330 --> 00:01:24,420 you not to skip it as firstly watching 46 00:01:27,890 --> 00:01:26,340 it supports toe directly and then 47 00:01:29,990 --> 00:01:27,900 secondly they're fascinating companies 48 00:01:31,850 --> 00:01:30,000 in and of themselves additionally you'll 49 00:01:33,890 --> 00:01:31,860 hear from one more Trade coffee around 50 00:01:35,630 --> 00:01:33,900 the one and a half hour mark thank you 51 00:01:38,929 --> 00:01:35,640 and enjoy this theolocution between 52 00:01:41,090 --> 00:01:38,939 yoshabak and Michael Levin welcome both 53 00:01:42,649 --> 00:01:41,100 Professor Michael Evan and yoshabak it's 54 00:01:44,210 --> 00:01:42,659 an honor to have you on the toll podcast 55 00:01:46,069 --> 00:01:44,220 again both of you and then together 56 00:01:47,030 --> 00:01:46,079 right now thank you it's great to be 57 00:01:51,830 --> 00:01:47,040 here 58 00:01:53,330 --> 00:01:51,840 and look forward to this conversation I 59 00:01:55,910 --> 00:01:53,340 look forward to it as well so we'll 60 00:01:57,590 --> 00:01:55,920 start off with the question of what is 61 00:01:59,749 --> 00:01:57,600 it that you Michael find most 62 00:02:01,910 --> 00:01:59,759 interesting about yosho's work and then 63 00:02:03,230 --> 00:02:01,920 Yoshi will go for you toward Michael 64 00:02:05,870 --> 00:02:03,240 yeah 65 00:02:07,249 --> 00:02:05,880 um I really enjoy the uh the breadth so 66 00:02:08,930 --> 00:02:07,259 so I've been looking I think I've 67 00:02:10,609 --> 00:02:08,940 probably read almost everything on your 68 00:02:12,830 --> 00:02:10,619 on your website you know the short kind 69 00:02:15,830 --> 00:02:12,840 of blog pieces and everything and uh 70 00:02:17,990 --> 00:02:15,840 yeah I'm I'm uh I'm I'm a big fan of of 71 00:02:19,970 --> 00:02:18,000 the breadth of of tackling a lot of the 72 00:02:22,790 --> 00:02:19,980 different issues that you do with 73 00:02:25,369 --> 00:02:22,800 respect to uh you know computation and 74 00:02:27,050 --> 00:02:25,379 and cognition and Ai and uh you know and 75 00:02:28,729 --> 00:02:27,060 ethics and everything I I really like 76 00:02:32,270 --> 00:02:28,739 that aspect of it so 77 00:02:36,470 --> 00:02:32,280 then you're sure yeah my apologies my 78 00:02:39,229 --> 00:02:36,480 blog is not up to date I haven't uh 79 00:02:40,670 --> 00:02:39,239 done any updates for a few years now on 80 00:02:44,449 --> 00:02:40,680 it I think 81 00:02:46,610 --> 00:02:44,459 um so of course I'm still in the Pro 82 00:02:50,449 --> 00:02:46,620 process of progressing and having new 83 00:02:53,630 --> 00:02:50,459 ideas and the ideas that I had in recent 84 00:02:55,430 --> 00:02:53,640 years I have a great overlap with a lot 85 00:02:59,930 --> 00:02:55,440 of the things that you are working on 86 00:03:02,030 --> 00:02:59,940 and when I listen to your Lex podcast 87 00:03:04,850 --> 00:03:02,040 last night there were many thoughts that 88 00:03:05,630 --> 00:03:04,860 you had that I had stumbled on 89 00:03:07,670 --> 00:03:05,640 um 90 00:03:09,170 --> 00:03:07,680 uh that I've never heard from anybody 91 00:03:11,030 --> 00:03:09,180 else and so I found this very 92 00:03:12,770 --> 00:03:11,040 fascinating and thought 93 00:03:14,449 --> 00:03:12,780 um maybe let's look at some of these 94 00:03:16,009 --> 00:03:14,459 thoughts first and then go from there 95 00:03:19,670 --> 00:03:16,019 and expand 96 00:03:22,610 --> 00:03:19,680 um Beyond those ideas but uh I for 97 00:03:23,869 --> 00:03:22,620 instance found after thinking about how 98 00:03:25,790 --> 00:03:23,879 cells work 99 00:03:27,530 --> 00:03:25,800 kind of obvious but missed by most 100 00:03:29,930 --> 00:03:27,540 people in Neuroscience or in science in 101 00:03:33,290 --> 00:03:29,940 general is that every cell has the 102 00:03:35,509 --> 00:03:33,300 ability to send multiple message types 103 00:03:37,190 --> 00:03:35,519 and receive multiple message types and 104 00:03:38,750 --> 00:03:37,200 do this conditionally and learn an 105 00:03:41,210 --> 00:03:38,760 average conditions to do that and to 106 00:03:43,430 --> 00:03:41,220 modulate this also every cell is an 107 00:03:45,170 --> 00:03:43,440 individual reinforcement learning agent 108 00:03:47,210 --> 00:03:45,180 single-sided animal that tries to 109 00:03:48,890 --> 00:03:47,220 survive by cooperating with its 110 00:03:50,210 --> 00:03:48,900 environment gets most of its rewards 111 00:03:53,750 --> 00:03:50,220 from its environment 112 00:03:55,789 --> 00:03:53,760 and as a result this means that every 113 00:03:58,490 --> 00:03:55,799 cell can in principle function like a 114 00:04:00,289 --> 00:03:58,500 neuron it can fulfill the same learning 115 00:04:02,690 --> 00:04:00,299 and information processing tasks as a 116 00:04:04,550 --> 00:04:02,700 new one the only difference that exists 117 00:04:07,550 --> 00:04:04,560 with respect to neurons or the main 118 00:04:09,589 --> 00:04:07,560 difference is that they cannot do this 119 00:04:12,589 --> 00:04:09,599 over very long distances because they 120 00:04:14,750 --> 00:04:12,599 are mostly connected only to the cells 121 00:04:16,729 --> 00:04:14,760 that are directly adjacent of course new 122 00:04:18,710 --> 00:04:16,739 ones also only communicate to adjacent 123 00:04:20,569 --> 00:04:18,720 cells but the adjacency of neurons is 124 00:04:22,610 --> 00:04:20,579 such that they have Excellence parts of 125 00:04:24,950 --> 00:04:22,620 the cell that reach very far through the 126 00:04:28,189 --> 00:04:24,960 organism so in some sense in your one is 127 00:04:31,310 --> 00:04:28,199 a telegraph cell that uses very specific 128 00:04:33,530 --> 00:04:31,320 messages that are encoded in a way like 129 00:04:35,330 --> 00:04:33,540 Morsi signals in extremely short high 130 00:04:37,129 --> 00:04:35,340 energy bursts that allow to send 131 00:04:40,490 --> 00:04:37,139 messages over the very long distances 132 00:04:42,830 --> 00:04:40,500 very quickly to move the muscles of an 133 00:04:43,790 --> 00:04:42,840 animal at the limit of what physics 134 00:04:45,770 --> 00:04:43,800 allows 135 00:04:48,350 --> 00:04:45,780 so it can compete with other animals and 136 00:04:50,030 --> 00:04:48,360 search for food and in order to make 137 00:04:52,010 --> 00:04:50,040 that happen it also needs to have a 138 00:04:54,110 --> 00:04:52,020 model of the world that gets updated at 139 00:04:56,330 --> 00:04:54,120 this higher rate so there is going to be 140 00:04:58,909 --> 00:04:56,340 an information processing system that is 141 00:05:00,230 --> 00:04:58,919 duplicating basically this cellular 142 00:05:03,230 --> 00:05:00,240 brain that is made from all the other 143 00:05:04,610 --> 00:05:03,240 cells in the body of the organism and at 144 00:05:06,469 --> 00:05:04,620 some point these two systems get 145 00:05:09,110 --> 00:05:06,479 decoupled they have their own codes 146 00:05:11,810 --> 00:05:09,120 their own language so to speak and but 147 00:05:14,150 --> 00:05:11,820 it still makes sense I guess to see the 148 00:05:16,670 --> 00:05:14,160 brain as a telegraphic extension of the 149 00:05:19,430 --> 00:05:16,680 community of cells in the body and for 150 00:05:21,830 --> 00:05:19,440 me this Insight that I stumbled on just 151 00:05:23,570 --> 00:05:21,840 because means and motive that Evolution 152 00:05:25,189 --> 00:05:23,580 would equip cells with doing that 153 00:05:27,770 --> 00:05:25,199 information processing if the organism 154 00:05:29,870 --> 00:05:27,780 is long enough lives long enough and if 155 00:05:31,790 --> 00:05:29,880 the cells share common genetic Destiny 156 00:05:34,189 --> 00:05:31,800 so they can get attuned to each other in 157 00:05:36,710 --> 00:05:34,199 an organism that basically every 158 00:05:39,890 --> 00:05:36,720 organism has the potential to become 159 00:05:43,550 --> 00:05:39,900 intelligent and if it gets old enough to 160 00:05:46,430 --> 00:05:43,560 process enough data to get to a very 161 00:05:49,010 --> 00:05:46,440 high degree of understanding of its 162 00:05:51,170 --> 00:05:49,020 environment in principle so of course a 163 00:05:53,810 --> 00:05:51,180 normal houseplant is not going to get 164 00:05:55,490 --> 00:05:53,820 very old with compared to us because the 165 00:05:57,890 --> 00:05:55,500 information processing is so much slower 166 00:06:00,409 --> 00:05:57,900 so they're not going to be very smart 167 00:06:02,210 --> 00:06:00,419 but at the level of ecosystems it's 168 00:06:04,310 --> 00:06:02,220 conceivable that there is quite 169 00:06:06,409 --> 00:06:04,320 considerable intelligence and then I 170 00:06:09,409 --> 00:06:06,419 stumbled on this notion that our 171 00:06:11,270 --> 00:06:09,419 ancestors thought that one day in 172 00:06:15,290 --> 00:06:11,280 Fairyland equals seven years in human 173 00:06:18,170 --> 00:06:15,300 land which is taught in the Artemis and 174 00:06:20,090 --> 00:06:18,180 also I just at some point I revised my 175 00:06:22,610 --> 00:06:20,100 notion of what the spirit is for 176 00:06:24,409 --> 00:06:22,620 instance is a spirit is it's an old bird 177 00:06:26,330 --> 00:06:24,419 for the operating system for an 178 00:06:29,029 --> 00:06:26,340 autonomous robot 179 00:06:31,010 --> 00:06:29,039 and the event this word was invented the 180 00:06:33,110 --> 00:06:31,020 um only autonomous robots that were 181 00:06:35,809 --> 00:06:33,120 known were people and plants and animals 182 00:06:38,029 --> 00:06:35,819 and nation states and ecosystems 183 00:06:41,510 --> 00:06:38,039 right whatever no robots built by people 184 00:06:44,629 --> 00:06:41,520 yet but uh there was this pattern of 185 00:06:46,550 --> 00:06:44,639 control in it that people could observe 186 00:06:48,469 --> 00:06:46,560 that was not directly tied to the 187 00:06:51,409 --> 00:06:48,479 hardware that was realized by the 188 00:06:53,150 --> 00:06:51,419 hardware but disembodied in a way and 189 00:06:55,850 --> 00:06:53,160 this notion of several is something that 190 00:06:57,830 --> 00:06:55,860 we lost after the enlightenment when we 191 00:07:00,529 --> 00:06:57,840 tried to deal with the 192 00:07:03,050 --> 00:07:00,539 um wrong Christian metaphysics and 193 00:07:04,430 --> 00:07:03,060 Superstition that came with it and threw 194 00:07:06,050 --> 00:07:04,440 out a lot of babies with the bath water 195 00:07:08,510 --> 00:07:06,060 and suddenly we basically lost a lot of 196 00:07:11,090 --> 00:07:08,520 Concepts especially this concept of 197 00:07:13,730 --> 00:07:11,100 software that existed before in a way 198 00:07:16,309 --> 00:07:13,740 this a software being a control pattern 199 00:07:17,570 --> 00:07:16,319 or a pattern of course a structure that 200 00:07:20,330 --> 00:07:17,580 exists at a certain level of course 201 00:07:22,850 --> 00:07:20,340 graining as some type of very very 202 00:07:26,230 --> 00:07:22,860 specific physical law that he exists by 203 00:07:29,990 --> 00:07:26,240 looking at reality from a certain angle 204 00:07:33,950 --> 00:07:30,000 and what I liked about your work is that 205 00:07:36,350 --> 00:07:33,960 you systematically have focused on this 206 00:07:38,270 --> 00:07:36,360 direction of what their can do that a 207 00:07:40,309 --> 00:07:38,280 cell is an agent and that levels of 208 00:07:43,730 --> 00:07:40,319 agency emerge in the interaction between 209 00:07:46,430 --> 00:07:43,740 cells and and you use a very clear 210 00:07:48,830 --> 00:07:46,440 language and uh clear Concepts and you 211 00:07:50,450 --> 00:07:48,840 obviously are driven by questions that 212 00:07:52,790 --> 00:07:50,460 you want to answer which is unusual in 213 00:07:55,730 --> 00:07:52,800 science I found that most of our 214 00:07:57,830 --> 00:07:55,740 contemporaries in science get broken it 215 00:08:01,189 --> 00:07:57,840 if it doesn't happen earlier during the 216 00:08:04,070 --> 00:08:01,199 PHD into people who apply methods in 217 00:08:05,570 --> 00:08:04,080 teams instead of people who join 218 00:08:06,830 --> 00:08:05,580 Academia because they think it's the 219 00:08:08,990 --> 00:08:06,840 most valuable thing they can do with 220 00:08:10,430 --> 00:08:09,000 their lives to pursue questions that 221 00:08:12,589 --> 00:08:10,440 they are interested and want to make 222 00:08:14,089 --> 00:08:12,599 progress on 223 00:08:16,790 --> 00:08:14,099 all right Michael there's plenty to 224 00:08:17,450 --> 00:08:16,800 respond to yeah yeah lots of lots of 225 00:08:19,550 --> 00:08:17,460 ideas 226 00:08:21,409 --> 00:08:19,560 um yeah I think I think it's very uh 227 00:08:23,150 --> 00:08:21,419 your point is very interesting about you 228 00:08:24,589 --> 00:08:23,160 know what what it really what really 229 00:08:26,110 --> 00:08:24,599 fundamentally is the difference between 230 00:08:28,969 --> 00:08:26,120 neurons and other cells of course 231 00:08:30,589 --> 00:08:28,979 evolutionarily they're reusing Machinery 232 00:08:32,209 --> 00:08:30,599 that has been around for a very long 233 00:08:34,010 --> 00:08:32,219 time since the time of bacteria 234 00:08:36,469 --> 00:08:34,020 basically right so our multi our 235 00:08:38,990 --> 00:08:36,479 unicellular ancestors had a lot of the 236 00:08:40,790 --> 00:08:39,000 same machinery and and even I mean of 237 00:08:43,850 --> 00:08:40,800 course axons are very can be very long 238 00:08:45,350 --> 00:08:43,860 but but uh there are sort of 239 00:08:47,150 --> 00:08:45,360 intermediate structures right there are 240 00:08:49,790 --> 00:08:47,160 tunneling nanotubes and things that 241 00:08:51,650 --> 00:08:49,800 allow cells to connect to maybe five or 242 00:08:53,690 --> 00:08:51,660 ten diameter cell diameters away right 243 00:08:55,610 --> 00:08:53,700 so so not terribly long but but also not 244 00:08:57,710 --> 00:08:55,620 immediate neighbors necessarily so that 245 00:08:59,930 --> 00:08:57,720 kind of architecture has been around for 246 00:09:00,889 --> 00:08:59,940 a while and people like roll so well 247 00:09:01,790 --> 00:09:00,899 look at 248 00:09:04,130 --> 00:09:01,800 um 249 00:09:06,530 --> 00:09:04,140 but a very brain-like electrical 250 00:09:09,769 --> 00:09:06,540 signaling in bacterial Colony so this is 251 00:09:12,769 --> 00:09:09,779 you know I think I think Evolution began 252 00:09:15,290 --> 00:09:12,779 to reuse this toolkit specifically of 253 00:09:16,550 --> 00:09:15,300 using this kind of communication to 254 00:09:18,290 --> 00:09:16,560 scale up 255 00:09:22,070 --> 00:09:18,300 um with the computational and other 256 00:09:24,050 --> 00:09:22,080 kinds of um other kinds of uh tricks uh 257 00:09:25,850 --> 00:09:24,060 yeah a really long time ago you know and 258 00:09:28,670 --> 00:09:25,860 I like to I like to imagine that if 259 00:09:30,230 --> 00:09:28,680 somebody had come to the people who were 260 00:09:32,389 --> 00:09:30,240 inventing connectionism and the first 261 00:09:33,949 --> 00:09:32,399 you know sort of perceptrons and neural 262 00:09:35,990 --> 00:09:33,959 networks and so on if somebody had come 263 00:09:37,910 --> 00:09:36,000 to them and said oh by the way sorry you 264 00:09:39,590 --> 00:09:37,920 know we're with the biologists we we got 265 00:09:41,509 --> 00:09:39,600 it wrong it's not the thinking isn't in 266 00:09:42,889 --> 00:09:41,519 the brain it's in the liver and so then 267 00:09:44,389 --> 00:09:42,899 the question is what would they do right 268 00:09:46,730 --> 00:09:44,399 what would they have changed anything 269 00:09:48,470 --> 00:09:46,740 about what they're doing and we said ah 270 00:09:50,210 --> 00:09:48,480 now we have to rethink our model or with 271 00:09:51,590 --> 00:09:50,220 is that fine who cares uh this is 272 00:09:53,750 --> 00:09:51,600 exactly the same the same model 273 00:09:55,130 --> 00:09:53,760 everything works just as well so I often 274 00:09:58,009 --> 00:09:55,140 I often think about that that that 275 00:10:01,190 --> 00:09:58,019 question what exactly do we mean by by 276 00:10:03,650 --> 00:10:01,200 neurons and isn't it interesting that we 277 00:10:07,250 --> 00:10:03,660 are able to to steal most of the tools 278 00:10:09,590 --> 00:10:07,260 the concepts the Frameworks the the math 279 00:10:12,110 --> 00:10:09,600 from neuroscience and apply it to 280 00:10:13,670 --> 00:10:12,120 problems in other spaces so not movement 281 00:10:15,170 --> 00:10:13,680 in three-dimensional space with muscles 282 00:10:16,850 --> 00:10:15,180 but for example movement through 283 00:10:18,829 --> 00:10:16,860 amorphous space right anatomical 284 00:10:20,329 --> 00:10:18,839 amorphous space the techniques can't 285 00:10:22,009 --> 00:10:20,339 tell the difference we use all the same 286 00:10:25,430 --> 00:10:22,019 stuff optogenetics neurotransmitter 287 00:10:28,850 --> 00:10:25,440 signaling we model active inference and 288 00:10:30,650 --> 00:10:28,860 uh we see perceptual by stability you 289 00:10:32,630 --> 00:10:30,660 name it you know we take Concepts from 290 00:10:35,389 --> 00:10:32,640 from neuroscience and we apply it out 291 00:10:37,850 --> 00:10:35,399 elsewhere in the body and uh generally 292 00:10:40,190 --> 00:10:37,860 speaking uh everything works exactly the 293 00:10:41,810 --> 00:10:40,200 same and that shows this I think what 294 00:10:45,949 --> 00:10:41,820 you were saying that there's this really 295 00:10:48,170 --> 00:10:45,959 interesting uh kind of um symmetry 296 00:10:49,310 --> 00:10:48,180 between these these uh that that a lot 297 00:10:50,930 --> 00:10:49,320 of the distinctions that we've been 298 00:10:52,550 --> 00:10:50,940 making are you know in terms of having 299 00:10:54,110 --> 00:10:52,560 different departments and different PHD 300 00:10:55,430 --> 00:10:54,120 programs and other things that say you 301 00:10:57,110 --> 00:10:55,440 know this is neuroscience this is 302 00:11:00,110 --> 00:10:57,120 developmental biology a lot of these 303 00:11:03,829 --> 00:11:00,120 things are just not um uh not as not as 304 00:11:06,350 --> 00:11:03,839 firm distinctions as we used to think 305 00:11:08,329 --> 00:11:06,360 yeah I suspect that people who insist on 306 00:11:12,170 --> 00:11:08,339 strong disciplinary boundaries do this 307 00:11:13,850 --> 00:11:12,180 out of of a protective impulse and what 308 00:11:16,850 --> 00:11:13,860 I noticed by I was studying many 309 00:11:19,190 --> 00:11:16,860 disciplines when I was young that 310 00:11:22,250 --> 00:11:19,200 um the different methodologies are so 311 00:11:23,870 --> 00:11:22,260 incompatible across fields that when I 312 00:11:26,150 --> 00:11:23,880 was studying philosophy 313 00:11:28,190 --> 00:11:26,160 um by or psychology I felt that computer 314 00:11:30,290 --> 00:11:28,200 scientists would be laughing about the 315 00:11:33,490 --> 00:11:30,300 methods that each of these fields are 316 00:11:36,650 --> 00:11:33,500 using to justify what they're doing and 317 00:11:39,650 --> 00:11:36,660 this I think is indicative of a defect 318 00:11:42,590 --> 00:11:39,660 because if you take science into the 319 00:11:44,690 --> 00:11:42,600 current regime of regulating it entirely 320 00:11:46,670 --> 00:11:44,700 by peer review there is no external 321 00:11:48,650 --> 00:11:46,680 Authority even the grand authorities are 322 00:11:51,170 --> 00:11:48,660 mostly fields or people who have been 323 00:11:52,970 --> 00:11:51,180 trained in The Sciences in existing 324 00:11:54,710 --> 00:11:52,980 paradigms and then are finding the 325 00:11:55,430 --> 00:11:54,720 continuation of those paradigms from the 326 00:11:57,250 --> 00:11:55,440 outside 327 00:12:00,110 --> 00:11:57,260 this um 328 00:12:02,210 --> 00:12:00,120 meta paradigmatic thinking it does not 329 00:12:04,550 --> 00:12:02,220 really exist that much in a 330 00:12:05,990 --> 00:12:04,560 peer-reviewed paradigm and ultimately 331 00:12:08,090 --> 00:12:06,000 when you do peer review for a couple 332 00:12:09,769 --> 00:12:08,100 Generations it also means that if your 333 00:12:11,329 --> 00:12:09,779 peers deteriorate there is nothing who 334 00:12:14,690 --> 00:12:11,339 pulls your science back 335 00:12:16,610 --> 00:12:14,700 and uh what I missed specifically in a 336 00:12:18,170 --> 00:12:16,620 lot of the way which Neuroscience is 337 00:12:19,430 --> 00:12:18,180 done is what you call the engineering 338 00:12:22,130 --> 00:12:19,440 stance 339 00:12:23,509 --> 00:12:22,140 and this engineering sense is very 340 00:12:25,130 --> 00:12:23,519 powerful and you get it automatically 341 00:12:26,930 --> 00:12:25,140 when you're a computer scientist because 342 00:12:28,850 --> 00:12:26,940 you don't really care about language is 343 00:12:31,430 --> 00:12:28,860 it written in what you care in is what 344 00:12:34,069 --> 00:12:31,440 causal pattern is realized and how can 345 00:12:36,410 --> 00:12:34,079 this be realized and how could I do it 346 00:12:38,389 --> 00:12:36,420 how would I do it how can Evolution do 347 00:12:40,850 --> 00:12:38,399 it what it means are it is disposal and 348 00:12:42,590 --> 00:12:40,860 this determines the search space for the 349 00:12:44,750 --> 00:12:42,600 things that I'm looking for but this 350 00:12:47,889 --> 00:12:44,760 requires that I think in causal systems 351 00:12:50,690 --> 00:12:47,899 and this thinking and causal systems is 352 00:12:52,430 --> 00:12:50,700 not impossible to it's possible not to 353 00:12:54,829 --> 00:12:52,440 do for a computer scientist 354 00:12:56,990 --> 00:12:54,839 but it is unusual outside of computer 355 00:12:59,210 --> 00:12:57,000 science and once you realize that it's 356 00:13:01,069 --> 00:12:59,220 it's very weird and suddenly you have 357 00:13:04,009 --> 00:13:01,079 Notions that try to replace causal 358 00:13:06,470 --> 00:13:04,019 structure with say evidence and then you 359 00:13:09,290 --> 00:13:06,480 notice that uh for instance evidence 360 00:13:11,030 --> 00:13:09,300 medicine is is not about uh 361 00:13:12,769 --> 00:13:11,040 probabilities of how something is 362 00:13:14,509 --> 00:13:12,779 realized and must work like you see 363 00:13:16,670 --> 00:13:14,519 people on the cruise ship getting 364 00:13:19,129 --> 00:13:16,680 infected over distances and you think oh 365 00:13:20,629 --> 00:13:19,139 this must be upward but no there is no 366 00:13:22,790 --> 00:13:20,639 peer control study so there is no 367 00:13:24,410 --> 00:13:22,800 evidence that it's airport and when you 368 00:13:26,090 --> 00:13:24,420 look at resistive planes from the 369 00:13:29,389 --> 00:13:26,100 outside like in this case the medical 370 00:13:32,269 --> 00:13:29,399 profession or the medical messaging and 371 00:13:35,150 --> 00:13:32,279 decision making or um I get terrified 372 00:13:37,190 --> 00:13:35,160 because it directly affects us and in 373 00:13:39,170 --> 00:13:37,200 terms of Neuroscience um of course 374 00:13:41,750 --> 00:13:39,180 there's more theoretical for the most 375 00:13:43,850 --> 00:13:41,760 part but there must be a reason why it's 376 00:13:46,910 --> 00:13:43,860 for the most part a theoretical because 377 00:13:49,670 --> 00:13:46,920 why there is no causal model that 378 00:13:51,949 --> 00:13:49,680 clinicians can use to explain uh what is 379 00:13:54,470 --> 00:13:51,959 happening in certain syndromes that 380 00:13:58,550 --> 00:13:54,480 people are exhibiting and I noticed this 381 00:14:01,069 --> 00:13:58,560 when I go to a doctor and even at a 382 00:14:02,870 --> 00:14:01,079 reputable institution like Stanford that 383 00:14:04,990 --> 00:14:02,880 most of the neuroscientists at some 384 00:14:07,009 --> 00:14:05,000 level there are of most of the 385 00:14:09,889 --> 00:14:07,019 neurologists that I'm talking towards us 386 00:14:13,790 --> 00:14:09,899 at some level dual lists that they uh 387 00:14:15,829 --> 00:14:13,800 don't have causal model of of the way in 388 00:14:18,530 --> 00:14:15,839 which the brain is realizing things and 389 00:14:21,050 --> 00:14:18,540 a lot of studies which discover that 390 00:14:22,910 --> 00:14:21,060 very simple mechanisms like the ability 391 00:14:24,949 --> 00:14:22,920 of human beings to use grammatical 392 00:14:26,750 --> 00:14:24,959 structure are actually reflected in the 393 00:14:28,550 --> 00:14:26,760 brain this is so amazing would have 394 00:14:31,870 --> 00:14:28,560 thought 395 00:14:35,269 --> 00:14:33,650 developments that existed in computer 396 00:14:36,769 --> 00:14:35,279 science have letters on a completely 397 00:14:40,430 --> 00:14:36,779 different track there is uh the 398 00:14:42,350 --> 00:14:40,440 perceptron is vaguely inspired by what 399 00:14:44,449 --> 00:14:42,360 the brain might be doing but I think 400 00:14:46,850 --> 00:14:44,459 it's it's really a toy model or a 401 00:14:48,650 --> 00:14:46,860 caricature of what cells are doing and 402 00:14:51,530 --> 00:14:48,660 not in the sense that it's inferior it's 403 00:14:54,110 --> 00:14:51,540 amazing what you can put forth with the 404 00:14:56,210 --> 00:14:54,120 modern perceptron variations right the 405 00:14:59,090 --> 00:14:56,220 current machine learning systems are 406 00:15:00,350 --> 00:14:59,100 mind-blowing and what they can do but 407 00:15:02,210 --> 00:15:00,360 they don't do it like biological 408 00:15:05,509 --> 00:15:02,220 organisms at all it's it's very 409 00:15:09,410 --> 00:15:05,519 different cells do not form change in 410 00:15:12,170 --> 00:15:09,420 which they wait uh sums of real numbers 411 00:15:14,210 --> 00:15:12,180 that there is something going on that is 412 00:15:15,769 --> 00:15:14,220 roughly similar to it but there's a 413 00:15:17,750 --> 00:15:15,779 self-organizing system that designs 414 00:15:19,370 --> 00:15:17,760 itself from the inside out not by a 415 00:15:21,410 --> 00:15:19,380 measure learning principle that applies 416 00:15:23,269 --> 00:15:21,420 to the outside and updates weights after 417 00:15:25,490 --> 00:15:23,279 reading and comparing them and Computing 418 00:15:27,949 --> 00:15:25,500 gradients to the system so this 419 00:15:30,650 --> 00:15:27,959 perspective of local surf organization 420 00:15:33,769 --> 00:15:30,660 by reinforcement agents that try to 421 00:15:35,090 --> 00:15:33,779 trade rewards with each other that is a 422 00:15:37,490 --> 00:15:35,100 perspective that I find totally 423 00:15:40,670 --> 00:15:37,500 fascinating and I wish this would have 424 00:15:43,009 --> 00:15:40,680 come and from Neuroscience into computer 425 00:15:44,449 --> 00:15:43,019 science but it hasn't there are some 426 00:15:46,310 --> 00:15:44,459 people which have thought about these 427 00:15:48,769 --> 00:15:46,320 ideas to some degree but there's been 428 00:15:50,990 --> 00:15:48,779 very little cross-pollination and I 429 00:15:53,090 --> 00:15:51,000 think all this talk of Neuroscience uh 430 00:15:55,389 --> 00:15:53,100 influencing computer science is mostly 431 00:15:58,910 --> 00:15:55,399 visual thinking 432 00:16:00,590 --> 00:15:58,920 yeah it's also uh I find uh this you 433 00:16:02,509 --> 00:16:00,600 know what you were saying about the 434 00:16:05,629 --> 00:16:02,519 different disciplines it's it's kind of 435 00:16:06,470 --> 00:16:05,639 amazing how uh well when I when I give a 436 00:16:07,910 --> 00:16:06,480 talk 437 00:16:10,189 --> 00:16:07,920 um I can always tell which department 438 00:16:12,470 --> 00:16:10,199 I'm in by by which part of the talk 439 00:16:13,910 --> 00:16:12,480 makes people uncomfortable and upset and 440 00:16:15,590 --> 00:16:13,920 it's always different depending on which 441 00:16:16,910 --> 00:16:15,600 department it is right so so there are 442 00:16:18,710 --> 00:16:16,920 things you can say in one Department 443 00:16:19,970 --> 00:16:18,720 that are completely obvious and you say 444 00:16:21,470 --> 00:16:19,980 this in the in another group of people 445 00:16:22,970 --> 00:16:21,480 and they they throw tomatoes they think 446 00:16:26,750 --> 00:16:22,980 this is just crazy for instance 447 00:16:28,730 --> 00:16:26,760 uh for for instance um I could I could 448 00:16:31,189 --> 00:16:28,740 uh say in you know in in a neuroscience 449 00:16:34,250 --> 00:16:31,199 Department I could say uh information 450 00:16:35,810 --> 00:16:34,260 can be processed is without changes in 451 00:16:36,949 --> 00:16:35,820 gene expression you don't need changes 452 00:16:38,769 --> 00:16:36,959 in gene expression to process 453 00:16:40,850 --> 00:16:38,779 information because the the the 454 00:16:42,530 --> 00:16:40,860 processing inside a neural network that 455 00:16:44,990 --> 00:16:42,540 runs on the physics of of action 456 00:16:46,370 --> 00:16:45,000 potentials right so I mean so right so 457 00:16:47,689 --> 00:16:46,380 so you can do all kinds of interesting 458 00:16:48,949 --> 00:16:47,699 information processing and you don't 459 00:16:50,269 --> 00:16:48,959 need genetic change sort of 460 00:16:51,829 --> 00:16:50,279 transcriptional or genetic change for 461 00:16:53,269 --> 00:16:51,839 that if I say the same thing in a 462 00:16:55,249 --> 00:16:53,279 molecular genetics department that say 463 00:16:57,050 --> 00:16:55,259 hey these cells could be processing tons 464 00:16:58,670 --> 00:16:57,060 of information long before the the 465 00:17:00,590 --> 00:16:58,680 transcriptome ever finds out about it 466 00:17:02,329 --> 00:17:00,600 this is this is considered you know just 467 00:17:04,970 --> 00:17:02,339 just completely wild because because 468 00:17:06,590 --> 00:17:04,980 it's thought that that that most of the 469 00:17:08,510 --> 00:17:06,600 hard work or in fact all of the hard 470 00:17:10,309 --> 00:17:08,520 work is done in in gene regulatory 471 00:17:12,770 --> 00:17:10,319 circuits and things like that right 472 00:17:15,770 --> 00:17:12,780 there are other other examples if I say 473 00:17:17,870 --> 00:17:15,780 um uh here's a uh here's a collection of 474 00:17:20,329 --> 00:17:17,880 cells that communicate electrically to 475 00:17:24,289 --> 00:17:20,339 to remember a particular spatial pattern 476 00:17:25,490 --> 00:17:24,299 again molecular cell biology that's what 477 00:17:27,409 --> 00:17:25,500 do you mean how can how can a collection 478 00:17:29,270 --> 00:17:27,419 of cells remember a spatial pattern but 479 00:17:30,530 --> 00:17:29,280 again in Neuroscience or in in an 480 00:17:32,690 --> 00:17:30,540 engineering department yeah of course 481 00:17:34,190 --> 00:17:32,700 the the of course they have electrical 482 00:17:36,110 --> 00:17:34,200 circuits that remember patterns and can 483 00:17:38,090 --> 00:17:36,120 do pattern completion and things like 484 00:17:40,190 --> 00:17:38,100 that so 485 00:17:42,110 --> 00:17:40,200 um you know views of views of causality 486 00:17:43,730 --> 00:17:42,120 views of uh just just lots of things 487 00:17:46,430 --> 00:17:43,740 like that that are that are very obvious 488 00:17:49,430 --> 00:17:46,440 uh to one group of people is completely 489 00:17:51,770 --> 00:17:49,440 taboo elsewhere so that that that 490 00:17:53,990 --> 00:17:51,780 distinction and and and and yeah and as 491 00:17:56,510 --> 00:17:54,000 as you as Joshua just said 492 00:17:58,549 --> 00:17:56,520 um it impacts it impacts everything it 493 00:18:01,970 --> 00:17:58,559 impacts education it impacts grants you 494 00:18:03,770 --> 00:18:01,980 know Grant reviews because when these 495 00:18:06,110 --> 00:18:03,780 kind of interdisciplinary grants come up 496 00:18:07,549 --> 00:18:06,120 the study sections have a really hard 497 00:18:09,409 --> 00:18:07,559 time finding people that can actually 498 00:18:11,630 --> 00:18:09,419 review them because what often happens 499 00:18:14,450 --> 00:18:11,640 is you'll find you'll you'll get a some 500 00:18:16,370 --> 00:18:14,460 kind of computational biology Grant and 501 00:18:17,990 --> 00:18:16,380 you put a proposal and you'll have some 502 00:18:19,850 --> 00:18:18,000 people on the on the panel who are 503 00:18:21,950 --> 00:18:19,860 biologists and some people who are the 504 00:18:23,510 --> 00:18:21,960 computational folks and it's very hard 505 00:18:25,070 --> 00:18:23,520 to get people that actually can 506 00:18:27,049 --> 00:18:25,080 appreciate both sides of it and 507 00:18:28,850 --> 00:18:27,059 understand what's happening together 508 00:18:30,409 --> 00:18:28,860 right so they will sort of each critique 509 00:18:32,570 --> 00:18:30,419 a certain part of it and the other part 510 00:18:35,390 --> 00:18:32,580 they say I don't know what this is and 511 00:18:37,310 --> 00:18:35,400 and as a result grants like that don't 512 00:18:39,230 --> 00:18:37,320 tend to not have a champion you know one 513 00:18:40,549 --> 00:18:39,240 person who can say no I get I get the 514 00:18:42,049 --> 00:18:40,559 whole thing and I I think it's really 515 00:18:44,990 --> 00:18:42,059 good or not 516 00:18:47,510 --> 00:18:45,000 so yeah it's uh even to the point where 517 00:18:49,970 --> 00:18:47,520 I I'm often asked you know when when 518 00:18:52,190 --> 00:18:49,980 people want to you list me somewhere 519 00:18:53,750 --> 00:18:52,200 they'll say so so what what what are you 520 00:18:55,850 --> 00:18:53,760 you know what kind of what kind of uh 521 00:18:56,990 --> 00:18:55,860 what's your field and I I never know how 522 00:18:58,250 --> 00:18:57,000 to answer that question you know this 523 00:18:59,870 --> 00:18:58,260 day it's been 30 years I still don't 524 00:19:01,909 --> 00:18:59,880 know how to answer that question I I 525 00:19:03,529 --> 00:19:01,919 just can't boil it down to one you know 526 00:19:06,110 --> 00:19:03,539 it just wouldn't make any sense to to 527 00:19:07,909 --> 00:19:06,120 say any of the traditional um you know 528 00:19:09,830 --> 00:19:07,919 the traditional fields 529 00:19:11,630 --> 00:19:09,840 so what do you say yosha when someone 530 00:19:13,970 --> 00:19:11,640 asks you what field you're in 531 00:19:18,049 --> 00:19:13,980 and it depends on who's asking 532 00:19:20,630 --> 00:19:18,059 so for instance I found it quite useful 533 00:19:23,150 --> 00:19:20,640 to sometimes say and 534 00:19:23,990 --> 00:19:23,160 sorry I'm not a philosopher 535 00:19:26,690 --> 00:19:24,000 um 536 00:19:28,970 --> 00:19:26,700 but uh but this or 537 00:19:31,610 --> 00:19:28,980 um I'm not that interested in machine 538 00:19:33,830 --> 00:19:31,620 learning and I'm I did publish papers in 539 00:19:36,409 --> 00:19:33,840 philosophy and in machine learning but 540 00:19:39,289 --> 00:19:36,419 it's not my specialty in the sense that 541 00:19:41,210 --> 00:19:39,299 I need to identify with it and 542 00:19:43,610 --> 00:19:41,220 um in some sense I guess that these 543 00:19:46,610 --> 00:19:43,620 categories are important when you try to 544 00:19:48,409 --> 00:19:46,620 write a grant proposal or when you try 545 00:19:50,450 --> 00:19:48,419 to find a job in a particular 546 00:19:53,450 --> 00:19:50,460 institution and they need to fill a 547 00:19:55,190 --> 00:19:53,460 position but for me it's more what 548 00:19:56,570 --> 00:19:55,200 questions am I interested and what is 549 00:19:58,010 --> 00:19:56,580 the thing that I want to make progress 550 00:19:59,330 --> 00:19:58,020 on or what is the thing that I want to 551 00:20:03,710 --> 00:19:59,340 build right now 552 00:20:07,250 --> 00:20:03,720 and uh I guess that in terms of the 553 00:20:10,130 --> 00:20:07,260 intersection I'm a cognitive scientist 554 00:20:12,110 --> 00:20:10,140 so I was asking Michael prior to you 555 00:20:14,210 --> 00:20:12,120 joining yosha why is that Michael that 556 00:20:15,409 --> 00:20:14,220 you were doing podcasts and if I 557 00:20:16,970 --> 00:20:15,419 understand correctly part of the reason 558 00:20:18,289 --> 00:20:16,980 was because you think out loud and you 559 00:20:20,390 --> 00:20:18,299 like to hear the other person's thoughts 560 00:20:21,950 --> 00:20:20,400 and take notes and it Spurs your own and 561 00:20:23,510 --> 00:20:21,960 firstly like Michael you can correct me 562 00:20:25,730 --> 00:20:23,520 if that's incorrect and then secondly 563 00:20:27,710 --> 00:20:25,740 yoksha I'm curious for an answer for 564 00:20:30,049 --> 00:20:27,720 this the same question what is it that 565 00:20:32,510 --> 00:20:30,059 you get out of doing podcasts other than 566 00:20:33,710 --> 00:20:32,520 say some marketing for if you were 567 00:20:35,510 --> 00:20:33,720 promoting something which I don't 568 00:20:39,230 --> 00:20:35,520 imagine you are currently 569 00:20:41,990 --> 00:20:39,240 uh no I'm not bucketing anything I uh 570 00:20:46,130 --> 00:20:42,000 what I like about podcasts is the 571 00:20:48,289 --> 00:20:46,140 ability to publish something in a format 572 00:20:50,450 --> 00:20:48,299 that is engaging to an interesting to 573 00:20:54,409 --> 00:20:50,460 people who actually care about it 574 00:20:56,270 --> 00:20:54,419 I like this informal way of uh holding 575 00:20:58,310 --> 00:20:56,280 on to some ideas and also like 576 00:21:01,930 --> 00:20:58,320 conversations is a medium to develop 577 00:21:04,190 --> 00:21:01,940 thought is this space in which we can 578 00:21:06,710 --> 00:21:04,200 reflect on each other look into each 579 00:21:09,650 --> 00:21:06,720 other's minds interact with the ideas of 580 00:21:11,990 --> 00:21:09,660 others in real time uh the production 581 00:21:13,730 --> 00:21:12,000 format of a podcast creates a certain 582 00:21:16,190 --> 00:21:13,740 focus of the conversation that can be 583 00:21:19,370 --> 00:21:16,200 useful and it's a pleasant kind of 584 00:21:23,690 --> 00:21:19,380 tangent that focuses you to stay on task 585 00:21:25,970 --> 00:21:23,700 and I also found that uh it's genuinely 586 00:21:28,549 --> 00:21:25,980 useful to some people like uh with the 587 00:21:31,370 --> 00:21:28,559 feedback that I get is that uh people 588 00:21:34,010 --> 00:21:31,380 tell me I had this really important 589 00:21:36,169 --> 00:21:34,020 question and I found this allowed me to 590 00:21:38,810 --> 00:21:36,179 make a progress on it and I feel much 591 00:21:41,270 --> 00:21:38,820 better now about these questions I uh 592 00:21:43,250 --> 00:21:41,280 just clarified something for me that has 593 00:21:45,770 --> 00:21:43,260 plagued me for years and 594 00:21:48,289 --> 00:21:45,780 um put me on track to solving it or this 595 00:21:50,570 --> 00:21:48,299 is inspired the following work so it's a 596 00:21:53,330 --> 00:21:50,580 form of uh publishing ideas and getting 597 00:21:56,450 --> 00:21:53,340 them into circulation in our Global 598 00:21:59,390 --> 00:21:56,460 Health Minds that is very informal in a 599 00:22:02,750 --> 00:21:59,400 way but it's not useless and also it's 600 00:22:05,090 --> 00:22:02,760 uh believes me in in this instance at 601 00:22:07,250 --> 00:22:05,100 least of the work of cutting editing and 602 00:22:09,409 --> 00:22:07,260 so on uh but anyway so I'm very grateful 603 00:22:12,169 --> 00:22:09,419 that you provide the service of curating 604 00:22:14,990 --> 00:22:12,179 our conversation and putting a little 605 00:22:17,270 --> 00:22:15,000 form that is useful to other people 606 00:22:19,250 --> 00:22:17,280 yeah yeah there's something well the two 607 00:22:21,409 --> 00:22:19,260 two things I was thinking of one is that 608 00:22:22,970 --> 00:22:21,419 uh you know I mean I have conversations 609 00:22:24,230 --> 00:22:22,980 with people all day long about these 610 00:22:26,330 --> 00:22:24,240 issues right so people in my lab 611 00:22:27,830 --> 00:22:26,340 collaborators whatever and most of 612 00:22:29,630 --> 00:22:27,840 course the vast majority of those 613 00:22:31,250 --> 00:22:29,640 conversations are not recorded and they 614 00:22:33,230 --> 00:22:31,260 just sort of disappear into the ether 615 00:22:34,250 --> 00:22:33,240 and then I I take something away from it 616 00:22:36,649 --> 00:22:34,260 and the other person takes something 617 00:22:38,149 --> 00:22:36,659 away from it but I've often thought that 618 00:22:40,669 --> 00:22:38,159 wouldn't it be wouldn't isn't it a shame 619 00:22:42,649 --> 00:22:40,679 that all of this is uh just just kind of 620 00:22:44,450 --> 00:22:42,659 disappears and it would be amazing to to 621 00:22:45,950 --> 00:22:44,460 have have a record of it and of course 622 00:22:48,649 --> 00:22:45,960 not every conversation is you know as 623 00:22:51,110 --> 00:22:48,659 gold but but but a lot of them are are 624 00:22:53,510 --> 00:22:51,120 useful and interesting and uh there are 625 00:22:55,370 --> 00:22:53,520 plenty of people that um could could be 626 00:22:57,590 --> 00:22:55,380 interested in could could benefit from 627 00:22:59,510 --> 00:22:57,600 it so so I really like this aspect that 628 00:23:00,830 --> 00:22:59,520 uh we can have conversations and then 629 00:23:03,230 --> 00:23:00,840 they are you know sort of canned and 630 00:23:04,730 --> 00:23:03,240 they're out there for uh for for people 631 00:23:06,830 --> 00:23:04,740 who are who are interested the other 632 00:23:08,570 --> 00:23:06,840 kind of um aspect of it which I don't 633 00:23:11,390 --> 00:23:08,580 really understand but but it's kind of 634 00:23:13,610 --> 00:23:11,400 neat is that if when somebody when 635 00:23:16,669 --> 00:23:13,620 somebody asks me to uh pre-record a talk 636 00:23:19,010 --> 00:23:16,679 it takes crazy amount of time because 637 00:23:20,330 --> 00:23:19,020 because I keep stopping and realizing I 638 00:23:21,950 --> 00:23:20,340 could have said that better let me start 639 00:23:23,990 --> 00:23:21,960 from the beginning and and it's just 640 00:23:26,450 --> 00:23:24,000 it's it's an incredible ordeal whereas 641 00:23:29,210 --> 00:23:26,460 something like this that's real time uh 642 00:23:30,289 --> 00:23:29,220 I'm sure has as many you know mistakes 643 00:23:31,730 --> 00:23:30,299 and things that I would have rather 644 00:23:33,289 --> 00:23:31,740 fixed later but but you can't do that 645 00:23:34,549 --> 00:23:33,299 right so you just sort of go with it and 646 00:23:36,470 --> 00:23:34,559 that's it and then it's done and you can 647 00:23:38,930 --> 00:23:36,480 move on so so I like I like that 648 00:23:40,490 --> 00:23:38,940 real-time aspect of it because it just 649 00:23:42,470 --> 00:23:40,500 it just helps you to get the ideas out 650 00:23:45,169 --> 00:23:42,480 without getting hung up and and trying 651 00:23:46,789 --> 00:23:45,179 to redo things 50 times 652 00:23:50,930 --> 00:23:46,799 yeah it's a format that allows 653 00:23:54,470 --> 00:23:50,940 tentativity if we have published we have 654 00:23:56,450 --> 00:23:54,480 culture in sciences that requires us to 655 00:23:58,610 --> 00:23:56,460 publish the things that we can hope to 656 00:24:00,649 --> 00:23:58,620 prove and make the best proof that we 657 00:24:02,630 --> 00:24:00,659 can but when we have anything 658 00:24:05,690 --> 00:24:02,640 complicated especially when we take our 659 00:24:07,130 --> 00:24:05,700 engineering stance we often cannot prove 660 00:24:10,070 --> 00:24:07,140 how things work 661 00:24:11,750 --> 00:24:10,080 instead our answers are in the realm of 662 00:24:14,750 --> 00:24:11,760 the possible and we need to discuss the 663 00:24:16,970 --> 00:24:14,760 possibilities and there is a value in 664 00:24:19,130 --> 00:24:16,980 understanding these possibilities to 665 00:24:21,409 --> 00:24:19,140 direct our future experiments and the 666 00:24:23,810 --> 00:24:21,419 Practical work that we do to see what's 667 00:24:25,850 --> 00:24:23,820 actually the case and we don't really 668 00:24:29,270 --> 00:24:25,860 have a publication format for that right 669 00:24:30,770 --> 00:24:29,280 we don't get neuroscientists to publish 670 00:24:32,270 --> 00:24:30,780 their ideas on how the mind works 671 00:24:34,310 --> 00:24:32,280 because nobody has a theory that they 672 00:24:35,930 --> 00:24:34,320 can prove and as a result there is 673 00:24:37,850 --> 00:24:35,940 basically a vacuum where theories should 674 00:24:40,370 --> 00:24:37,860 be and the theory building happens 675 00:24:41,930 --> 00:24:40,380 informally in conversations that 676 00:24:45,169 --> 00:24:41,940 basically requires personal contact 677 00:24:46,850 --> 00:24:45,179 which is a big issue once conference has 678 00:24:49,370 --> 00:24:46,860 been virtual because that contact 679 00:24:50,690 --> 00:24:49,380 diminished and you get a lot of 680 00:24:53,450 --> 00:24:50,700 important ideas by reading the 681 00:24:55,370 --> 00:24:53,460 Publications and so on but this uh what 682 00:24:57,289 --> 00:24:55,380 could be or connecting the dots or 683 00:24:59,029 --> 00:24:57,299 possibilities or ideas that might be 684 00:25:01,490 --> 00:24:59,039 proven wrong later that we just exchange 685 00:25:03,049 --> 00:25:01,500 as in the status of ideas that is 686 00:25:04,850 --> 00:25:03,059 something that has a good place and a 687 00:25:11,029 --> 00:25:04,860 podcast 688 00:25:13,190 --> 00:25:11,039 something new so for instance I was 689 00:25:14,870 --> 00:25:13,200 thinking about this and I well podcasts 690 00:25:16,850 --> 00:25:14,880 go back a while and Brogan invented this 691 00:25:19,970 --> 00:25:16,860 long-form format or popularized it 692 00:25:21,649 --> 00:25:19,980 however on television there are 693 00:25:23,630 --> 00:25:21,659 interviews so there's Oprah and those 694 00:25:26,570 --> 00:25:23,640 are long one hour they're 60 minutes and 695 00:25:28,370 --> 00:25:26,580 then back in the 90s there was a three 696 00:25:30,169 --> 00:25:28,380 and a half hour it's essentially a 697 00:25:32,029 --> 00:25:30,179 podcast it's like Charlie Rose three and 698 00:25:34,669 --> 00:25:32,039 a half hour conversation it's like a 699 00:25:38,149 --> 00:25:34,679 Theo location with Freeman Dyson Daniel 700 00:25:41,330 --> 00:25:38,159 Dennett Stephen J Gould like the Rupert 701 00:25:43,370 --> 00:25:41,340 sheldrake all of those on the same one 702 00:25:46,370 --> 00:25:43,380 format it's essentially a podcast 703 00:25:47,810 --> 00:25:46,380 talking about metaphysics like man oh 704 00:25:49,250 --> 00:25:47,820 man I can't believe that got published 705 00:25:51,230 --> 00:25:49,260 and then also I think about it well did 706 00:25:52,669 --> 00:25:51,240 Plato have the first podcast 707 00:25:54,049 --> 00:25:52,679 because he's just publishing these 708 00:25:55,549 --> 00:25:54,059 dialogues and you read them but it's not 709 00:25:57,110 --> 00:25:55,559 as if maybe he would have published it 710 00:25:58,669 --> 00:25:57,120 in video I think Plato was the first 711 00:26:00,950 --> 00:25:58,679 podcaster 712 00:26:02,930 --> 00:26:00,960 so is there something new about this 713 00:26:05,090 --> 00:26:02,940 format of podcasting that wasn't there 714 00:26:07,130 --> 00:26:05,100 before or what's new about it I think 715 00:26:09,769 --> 00:26:07,140 it's like it's like vlogging uh blogging 716 00:26:12,950 --> 00:26:09,779 is also not new right being able to 717 00:26:15,890 --> 00:26:12,960 write text that you publish uh and uh 718 00:26:18,529 --> 00:26:15,900 people can follow about your writing and 719 00:26:20,570 --> 00:26:18,539 so on did exist in some sense before but 720 00:26:22,730 --> 00:26:20,580 uh the internet made it possible to 721 00:26:25,250 --> 00:26:22,740 publish this for everyone do you don't 722 00:26:26,870 --> 00:26:25,260 need a publisher anymore and you don't 723 00:26:28,490 --> 00:26:26,880 know your TV studio anymore you don't 724 00:26:30,529 --> 00:26:28,500 need a broadcast station that is 725 00:26:32,630 --> 00:26:30,539 recording your talk show and sends it to 726 00:26:35,450 --> 00:26:32,640 an audience there is no competition with 727 00:26:37,549 --> 00:26:35,460 other talk Source because uh there is no 728 00:26:40,190 --> 00:26:37,559 limitations on how many people can 729 00:26:42,710 --> 00:26:40,200 broadcast at the same time and this 730 00:26:45,649 --> 00:26:42,720 allows an enormous diversity and of 731 00:26:48,529 --> 00:26:45,659 thoughts and small Productions that are 732 00:26:50,570 --> 00:26:48,539 done at a very low cost lowering the 733 00:26:52,730 --> 00:26:50,580 threshold for putting something out 734 00:26:54,830 --> 00:26:52,740 there and seeing what happens so in this 735 00:26:57,110 --> 00:26:54,840 sense it's the ecosystem that emerged is 736 00:26:59,210 --> 00:26:57,120 new because a variable change that 737 00:27:00,529 --> 00:26:59,220 changed the cost of producing a talk 738 00:27:02,149 --> 00:27:00,539 show 739 00:27:03,950 --> 00:27:02,159 all right 740 00:27:06,470 --> 00:27:03,960 Michael you agree 741 00:27:09,590 --> 00:27:06,480 um yeah yeah I mean yes that and and all 742 00:27:12,169 --> 00:27:09,600 of that and also just the fact that you 743 00:27:13,669 --> 00:27:12,179 know uh as you as you just said uh these 744 00:27:15,769 --> 00:27:13,679 kind of like long form things were 745 00:27:16,850 --> 00:27:15,779 fairly rare so most of the time if 746 00:27:18,649 --> 00:27:16,860 you're going to be in one of the 747 00:27:20,630 --> 00:27:18,659 traditional media they tell you okay 748 00:27:22,310 --> 00:27:20,640 you've got the you've got you know three 749 00:27:23,570 --> 00:27:22,320 minutes uh you know we're gonna cut all 750 00:27:25,549 --> 00:27:23,580 this stuff and we're gonna boil it down 751 00:27:27,169 --> 00:27:25,559 to three minutes and this this is often 752 00:27:28,669 --> 00:27:27,179 incredibly frustrating and and I 753 00:27:31,010 --> 00:27:28,679 understand I mean we're drowned in 754 00:27:32,570 --> 00:27:31,020 information and so so there's obviously 755 00:27:34,610 --> 00:27:32,580 a place for very short statement on 756 00:27:36,950 --> 00:27:34,620 things but the kind of stuff that we're 757 00:27:39,529 --> 00:27:36,960 talking about uh cannot be boiled down 758 00:27:41,570 --> 00:27:39,539 to to you know TV sound bites or 759 00:27:43,370 --> 00:27:41,580 anything it's just not and and so so the 760 00:27:45,350 --> 00:27:43,380 ability to have these long-form things 761 00:27:47,510 --> 00:27:45,360 so that anybody who wants to really dig 762 00:27:49,310 --> 00:27:47,520 in can hear what the actual thought is 763 00:27:52,430 --> 00:27:49,320 as opposed to something that's that's 764 00:27:54,950 --> 00:27:52,440 been just uh you know boiled into into a 765 00:27:57,049 --> 00:27:54,960 very um very very short statement I 766 00:27:58,430 --> 00:27:57,059 think is is invaluable just being able 767 00:28:01,430 --> 00:27:58,440 to have it out there for people to find 768 00:28:03,289

which had a 21.5 percent 818 00:29:42,350 --> 00:29:41,279 return so for instance if you were to 819 00:29:43,850 --> 00:29:42,360 put ten thousand dollars in you would 820 00:29:45,230 --> 00:29:43,860 now have twelve thousand Welcome to our 821 00:29:46,730 --> 00:29:45,240 new sponsor Masterworks and the link to 822 00:29:48,649 --> 00:29:46,740 them is in the description just so you 823 00:29:50,810 --> 00:29:48,659 know there's in fact a wait list to join 824 00:29:52,669 --> 00:29:50,820 their platform right now however total 825 00:29:54,529 --> 00:29:52,679 listeners can skip the wait list by 826 00:29:56,750 --> 00:29:54,539 visiting the link in the description as 827 00:29:58,669 --> 00:29:56,760 well as by using the promo code theories 828 00:30:00,110 --> 00:29:58,679 of everything again the link is in the 829 00:30:01,909 --> 00:30:00,120 description you can see important 830 00:30:05,330 --> 00:30:01,919 regulation A disclosures at Masterworks 831 00:30:07,549 --> 00:30:05,340 dot com slash CD what some stance of 832 00:30:09,529 --> 00:30:07,559 yours some belief that has changed most 833 00:30:11,389 --> 00:30:09,539 drastically in the past few years let's 834 00:30:13,250 --> 00:30:11,399 say three and it could be anywhere from 835 00:30:14,930 --> 00:30:13,260 something abstruse and academic to more 836 00:30:17,090 --> 00:30:14,940 colloquial like I didn't realize the 837 00:30:18,230 --> 00:30:17,100 value of children or I overvalued 838 00:30:20,750 --> 00:30:18,240 children now I'm stuck with them like 839 00:30:22,789 --> 00:30:20,760 geez that was a mistake 840 00:30:25,490 --> 00:30:22,799 yeah so something where I changed my 841 00:30:28,909 --> 00:30:25,500 mind was RNA based memory transfer 842 00:30:31,250 --> 00:30:28,919 and uh I think it's a super interesting 843 00:30:33,830 --> 00:30:31,260 idea in this context because it's uh 844 00:30:36,710 --> 00:30:33,840 close to uh stuff that Michael has been 845 00:30:38,450 --> 00:30:36,720 working on and is interested in uh there 846 00:30:41,510 --> 00:30:38,460 have been some experiments in the Soviet 847 00:30:46,070 --> 00:30:41,520 Union I think in the 70s where 848 00:30:47,930 --> 00:30:46,080 scientists look planaria uh trained them 849 00:30:49,430 --> 00:30:47,940 to learn something I think they were 850 00:30:51,649 --> 00:30:49,440 learned how to be afraid of electric 851 00:30:53,810 --> 00:30:51,659 shocks and things like that and then 852 00:30:55,970 --> 00:30:53,820 they put their uh the brains into a 853 00:30:57,710 --> 00:30:55,980 blender extracted the iron a injected 854 00:30:59,510 --> 00:30:57,720 other planaria visit and these other 855 00:31:02,870 --> 00:30:59,520 planaria had learned it 856 00:31:05,029 --> 00:31:02,880 and I I learned about this as a kid when 857 00:31:06,529 --> 00:31:05,039 I in the 1980s read Soviet science 858 00:31:09,889 --> 00:31:06,539 fiction into Twitter I grew up in 859 00:31:14,570 --> 00:31:09,899 Eastern Germany and the evil scientist 860 00:31:17,149 --> 00:31:14,580 uh harvested the brains of geniuses and 861 00:31:20,029 --> 00:31:17,159 injected himself is RNA extracted from 862 00:31:22,549 --> 00:31:20,039 these brains and thereby acquired the 863 00:31:25,430 --> 00:31:22,559 skills and even though I'm pretty sure 864 00:31:27,669 --> 00:31:25,440 it probably doesn't work if you if you 865 00:31:29,810 --> 00:31:27,679 do it at this level 866 00:31:33,110 --> 00:31:29,820 this was inspired by this original 867 00:31:37,210 --> 00:31:33,120 research and I later heard nothing about 868 00:31:41,029 --> 00:31:37,220 this anymore and so I dismissed it as uh 869 00:31:42,529 --> 00:31:41,039 similar things as I read in Sputnik and 870 00:31:44,630 --> 00:31:42,539 other Russian Publications which create 871 00:31:47,990 --> 00:31:44,640 their own methodological Universe about 872 00:31:50,330 --> 00:31:48,000 ball lightning that is authentic and 873 00:31:52,250 --> 00:31:50,340 possibly sentient and so on and 874 00:31:54,230 --> 00:31:52,260 dismissed this all as basically Another 875 00:31:56,570 --> 00:31:54,240 Universe of another Reader's Digest 876 00:31:58,970 --> 00:31:56,580 culture that is producing its own ideas 877 00:32:00,169 --> 00:31:58,980 that then later on get dissolved once 878 00:32:02,210 --> 00:32:00,179 science advanced answers because 879 00:32:03,649 --> 00:32:02,220 everybody knows it's it's synapses it's 880 00:32:05,690 --> 00:32:03,659 connections between neurons that matter 881 00:32:07,789 --> 00:32:05,700 the RNA is not that important for the 882 00:32:09,710 --> 00:32:07,799 information processing might change some 883 00:32:11,810 --> 00:32:09,720 state but you cannot learn something by 884 00:32:13,909 --> 00:32:11,820 extracting RNA and re-injecting it into 885 00:32:16,250 --> 00:32:13,919 the next organism because how would that 886 00:32:18,470 --> 00:32:16,260 work if it's done in the synapses 887 00:32:20,690 --> 00:32:18,480 and uh then recently there were some 888 00:32:22,490 --> 00:32:20,700 papers which replicated uh the original 889 00:32:24,190 --> 00:32:22,500 research and has been replicated from 890 00:32:28,730 --> 00:32:24,200 time to time 891 00:32:31,730 --> 00:32:28,740 in different types of organisms but to 892 00:32:34,850 --> 00:32:31,740 my knowledge not in of course macaques 893 00:32:36,830 --> 00:32:34,860 or not even mice but so it's not clear 894 00:32:39,409 --> 00:32:36,840 if their brains work according to the 895 00:32:41,350 --> 00:32:39,419 same principles as planaria but planaria 896 00:32:43,669 --> 00:32:41,360 are not 897 00:32:45,289 --> 00:32:43,679 extremely simple organisms only a 898 00:32:47,289 --> 00:32:45,299 handful of neurons there are something 899 00:32:49,789 --> 00:32:47,299 intermediate with some their main 900 00:32:51,230 --> 00:32:49,799 architecture is different from ours and 901 00:32:53,149 --> 00:32:51,240 their functioning principles of their 902 00:32:55,130 --> 00:32:53,159 neurons might be slightly different but 903 00:32:58,190 --> 00:32:55,140 it's worse following this idea and going 904 00:33:00,169 --> 00:32:58,200 down that rabbit hole and then I looked 905 00:33:02,090 --> 00:33:00,179 for my computer science engineering 906 00:33:04,250 --> 00:33:02,100 perspective and I realized that there 907 00:33:07,789 --> 00:33:04,260 are always things about the synaptic 908 00:33:10,250 --> 00:33:07,799 story that uh I find confusing because 909 00:33:12,649 --> 00:33:10,260 they're very difficult to implement 910 00:33:14,750 --> 00:33:12,659 so for instance weight sharing as a 911 00:33:16,070 --> 00:33:14,760 computer scientist I require weight 912 00:33:19,009 --> 00:33:16,080 sharing I don't know how to get around 913 00:33:21,049 --> 00:33:19,019 this if I want to entrain myself as 914 00:33:23,090 --> 00:33:21,059 computational Primitives in a local area 915 00:33:25,850 --> 00:33:23,100 of of my brain for instance the ability 916 00:33:28,909 --> 00:33:25,860 to rotate something which rotation is 917 00:33:31,549 --> 00:33:28,919 some operator that I apply on a pattern 918 00:33:32,990 --> 00:33:31,559 that allows this pattern to be 919 00:33:35,870 --> 00:33:33,000 represented in a slightly different way 920 00:33:38,090 --> 00:33:35,880 to have this object rotated a few 921 00:33:39,710 --> 00:33:38,100 degrees but an object doesn't consist of 922 00:33:42,830 --> 00:33:39,720 a single point it consists of many 923 00:33:44,630 --> 00:33:42,840 features that all need to get the same 924 00:33:47,509 --> 00:33:44,640 rotation applied to them using the same 925 00:33:49,970 --> 00:33:47,519 mathematical Primitives so how do you 926 00:33:53,269 --> 00:33:49,980 implement the same operator across an 927 00:33:55,909 --> 00:33:53,279 entire brain area do you make many many 928 00:33:57,769 --> 00:33:55,919 copies of the same pattern and computer 929 00:33:59,389 --> 00:33:57,779 scientists solve that with so-called 930 00:34:02,149 --> 00:33:59,399 convolutional neural networks which 931 00:34:04,810 --> 00:34:02,159 basically use the same weights again and 932 00:34:06,769 --> 00:34:04,820 again in different areas using only 933 00:34:08,570 --> 00:34:06,779 training them once and making them 934 00:34:11,149 --> 00:34:08,580 available everywhere and that would be 935 00:34:14,030 --> 00:34:11,159 very difficult to implement and synapses 936 00:34:16,430 --> 00:34:14,040 maybe there are ways but it's not 937 00:34:18,829 --> 00:34:16,440 straightforward another thing is if we 938 00:34:21,290 --> 00:34:18,839 see how training Works in babies they 939 00:34:22,909 --> 00:34:21,300 learn something and then they get rid of 940 00:34:24,290 --> 00:34:22,919 the Surplus synopsis initially they have 941 00:34:27,649 --> 00:34:24,300 much more connectivity than they need 942 00:34:29,930 --> 00:34:27,659 and uh when they get uh after they've 943 00:34:32,270 --> 00:34:29,940 trained they optimize the way in which 944 00:34:34,010 --> 00:34:32,280 the wiring works by discarding the 945 00:34:36,409 --> 00:34:34,020 things they don't need to compute what 946 00:34:39,470 --> 00:34:36,419 they want to compute so it's like 947 00:34:41,329 --> 00:34:39,480 calling the synapses it does not uh 948 00:34:43,369 --> 00:34:41,339 freeze or Edge the learning into the 949 00:34:45,730 --> 00:34:43,379 brain but it optimizes the energy usage 950 00:34:47,810 --> 00:34:45,740 of the brain another issue is that 951 00:34:49,490 --> 00:34:47,820 patterns of activation are not 952 00:34:51,589 --> 00:34:49,500 completely stable in the brain they in 953 00:34:53,389 --> 00:34:51,599 the cortex if you look you find that 954 00:34:55,190 --> 00:34:53,399 they might be moving the next day or 955 00:34:57,109 --> 00:34:55,200 even rotate a little bit which is also 956 00:34:58,790 --> 00:34:57,119 difficult to do with synapses you cannot 957 00:35:00,230 --> 00:34:58,800 read out the weights and copy them 958 00:35:02,810 --> 00:35:00,240 somewhere else in an easy 959 00:35:05,390 --> 00:35:02,820 straightforward fashion and another 960 00:35:07,370 --> 00:35:05,400 issue is defragmentation if you learn 961 00:35:08,089 --> 00:35:07,380 for instance your body map into a brain 962 00:35:10,310 --> 00:35:08,099 area 963 00:35:11,930 --> 00:35:10,320 and then somebody changes your body map 964 00:35:13,970 --> 00:35:11,940 because you have an accident and lose a 965 00:35:15,589 --> 00:35:13,980 finger or somebody gives you an 966 00:35:17,810 --> 00:35:15,599 artificial limp and you start to 967 00:35:19,490 --> 00:35:17,820 integrate this into your body map how do 968 00:35:21,589 --> 00:35:19,500 you shift all the representations around 969 00:35:23,810 --> 00:35:21,599 how do you make space for something else 970 00:35:26,150 --> 00:35:23,820 and move it or also initially when you 971 00:35:27,470 --> 00:35:26,160 set up your Maps via happier learning 972 00:35:29,870 --> 00:35:27,480 how do you make sure that the 973 00:35:31,550 --> 00:35:29,880 neighborhoods are always correct and you 974 00:35:33,589 --> 00:35:31,560 don't need to realign anything and I 975 00:35:35,810 --> 00:35:33,599 guess you need some kind of realignment 976 00:35:37,550 --> 00:35:35,820 and uh all these things seem to be 977 00:35:38,750 --> 00:35:37,560 possible when you switch to a different 978 00:35:41,750 --> 00:35:38,760 paradigm 979 00:35:44,030 --> 00:35:41,760 and uh this so if you take this RNA 980 00:35:47,210 --> 00:35:44,040 basically seriously go down this wrapper 981 00:35:49,609 --> 00:35:47,220 tool what you get is 982 00:35:52,190 --> 00:35:49,619 um the neurons are not learning a local 983 00:35:53,870 --> 00:35:52,200 function over its neighbors but they are 984 00:35:55,910 --> 00:35:53,880 learning how to respond to the shape of 985 00:35:57,650 --> 00:35:55,920 an incoming activation front 986 00:35:59,270 --> 00:35:57,660 right the spatial temporal pattern in 987 00:36:01,609 --> 00:35:59,280 their neighborhood and they are densely 988 00:36:04,849 --> 00:36:01,619 enough connected so the enabled is just 989 00:36:07,250 --> 00:36:04,859 the space around them and in this space 990 00:36:10,069 --> 00:36:07,260 they basically interpret this according 991 00:36:12,290 --> 00:36:10,079 to a certain topology to say this uh is 992 00:36:14,810 --> 00:36:12,300 maybe a convolution that gives me two 993 00:36:16,670 --> 00:36:14,820 and a half D or it gives me 2D or 1D or 994 00:36:20,750 --> 00:36:16,680 whatever the type of function is that 995 00:36:23,750 --> 00:36:20,760 they want to compute and they learn how 996 00:36:25,730 --> 00:36:23,760 to fire in this in response to those 997 00:36:27,170 --> 00:36:25,740 patterns and thereby modulate the 998 00:36:28,670 --> 00:36:27,180 patterns when they're passed on so the 999 00:36:31,670 --> 00:36:28,680 neurons act as something like a 1000 00:36:34,150 --> 00:36:31,680 self-modulating ether so which waveforms 1001 00:36:37,609 --> 00:36:34,160 propagate that perform the computations 1002 00:36:39,829 --> 00:36:37,619 and they store the responses to the 1003 00:36:43,250 --> 00:36:39,839 distributions of incoming signals 1004 00:36:45,829 --> 00:36:43,260 possibly in RNA so you have little mix 1005 00:36:48,230 --> 00:36:45,839 tapes little tape fragments that they 1006 00:36:50,390 --> 00:36:48,240 store in the Soma and that you can make 1007 00:36:52,310 --> 00:36:50,400 more of very cheaply and easily if they 1008 00:36:53,930 --> 00:36:52,320 are successful mixtapes and their useful 1009 00:36:55,490 --> 00:36:53,940 computational Primitives that they 1010 00:36:57,410 --> 00:36:55,500 discovered and they can distribute this 1011 00:37:00,230 --> 00:36:57,420 to other neurons through the entire 1012 00:37:02,030 --> 00:37:00,240 cortex so new ones of the same type will 1013 00:37:04,250 --> 00:37:02,040 gain the knowledge to apply the same 1014 00:37:06,650 --> 00:37:04,260 computational Primitives 1015 00:37:08,510 --> 00:37:06,660 and that is something I don't know if 1016 00:37:10,190 --> 00:37:08,520 the brain is doing that and of the human 1017 00:37:11,750 --> 00:37:10,200 brain is using these principles or if 1018 00:37:13,670 --> 00:37:11,760 it's using them a lot and how important 1019 00:37:15,829 --> 00:37:13,680 this is and how many other mechanisms 1020 00:37:17,630 --> 00:37:15,839 exist but it's a mechanism that we 1021 00:37:19,730 --> 00:37:17,640 haven't so my knowledge tried very much 1022 00:37:22,310 --> 00:37:19,740 in Ai and computer science 1023 00:37:25,130 --> 00:37:22,320 and it would work there is something 1024 00:37:27,170 --> 00:37:25,140 that is a very close analog that is a 1025 00:37:29,390 --> 00:37:27,180 neural cellular automaton 1026 00:37:31,430 --> 00:37:29,400 here so basically instead of learning 1027 00:37:33,290 --> 00:37:31,440 weight uh weight shifts or weight 1028 00:37:34,849 --> 00:37:33,300 changes between adjacent new ones what 1029 00:37:37,670 --> 00:37:34,859 you learn is 1030 00:37:40,069 --> 00:37:37,680 um Global functions that tell neurons on 1031 00:37:41,450 --> 00:37:40,079 how to respond to patterns in the 1032 00:37:44,030 --> 00:37:41,460 neighborhood 1033 00:37:46,550 --> 00:37:44,040 and these functions are the same for 1034 00:37:48,890 --> 00:37:46,560 every point in your Matrix 1035 00:37:51,650 --> 00:37:48,900 and you can learn arbitrary functions in 1036 00:37:53,329 --> 00:37:51,660 this way and what's nice about is that 1037 00:37:56,630 --> 00:37:53,339 you only need to learn computational 1038 00:37:59,510 --> 00:37:56,640 Primitives once our kubernetworks need 1039 00:38:01,130 --> 00:37:59,520 to learn the same linear algebra over 1040 00:38:03,650 --> 00:38:01,140 and over again in many different corners 1041 00:38:05,150 --> 00:38:03,660 of the neural network because you need a 1042 00:38:07,370 --> 00:38:05,160 vector algebra for many kinds of 1043 00:38:08,930 --> 00:38:07,380 operations that we perform like for 1044 00:38:11,450 --> 00:38:08,940 instance operations in space 1045 00:38:14,390 --> 00:38:11,460 where we shift things around or rotate 1046 00:38:15,650 --> 00:38:14,400 them and if they could change exchange 1047 00:38:17,870 --> 00:38:15,660 these useful 1048 00:38:19,430 --> 00:38:17,880 um operations with each other and just 1049 00:38:21,710 --> 00:38:19,440 apply an operator whenever the 1050 00:38:23,390 --> 00:38:21,720 environment uh dictates that this would 1051 00:38:25,310 --> 00:38:23,400 be a good idea to try to apply this 1052 00:38:27,530 --> 00:38:25,320 operator right now in this context that 1053 00:38:28,849 --> 00:38:27,540 could speed up learning it could make uh 1054 00:38:31,550 --> 00:38:28,859 training much more sample efficient 1055 00:38:33,109 --> 00:38:31,560 right so something super interesting to 1056 00:38:35,450 --> 00:38:33,119 try and this is one of the rabbit holes 1057 00:38:38,450 --> 00:38:35,460 I recently fell down whenever I changed 1058 00:38:41,810 --> 00:38:38,460 my thinking based on some experiment 1059 00:38:43,609 --> 00:38:41,820 from Neuroscience that doesn't have very 1060 00:38:46,250 --> 00:38:43,619 big impact for for the mainstream of 1061 00:38:49,329 --> 00:38:46,260 Neuroscience but that I found reflected 1062 00:38:51,470 --> 00:38:49,339 in Michael's work with planaria 1063 00:38:54,530 --> 00:38:51,480 yeah that's that's super interesting 1064 00:38:57,829 --> 00:38:54,540 stuff um I I can sprinkle a few a few 1065 00:39:00,589 --> 00:38:57,839 details onto this um uh the original so 1066 00:39:02,569 --> 00:39:00,599 so the original finding in planaria was 1067 00:39:04,609 --> 00:39:02,579 um was a guy named James McConnell in 1068 00:39:06,710 --> 00:39:04,619 the in in Michigan actually in the US 1069 00:39:08,450 --> 00:39:06,720 and and then that was in the 60s the 1070 00:39:10,670 --> 00:39:08,460 early 60s and then there were some 1071 00:39:12,650 --> 00:39:10,680 really interesting Russian work um that 1072 00:39:14,810 --> 00:39:12,660 that picked it up after that uh we 1073 00:39:17,150 --> 00:39:14,820 reproduced some of it recently in using 1074 00:39:19,069 --> 00:39:17,160 modern uh modern quantitative uh 1075 00:39:20,810 --> 00:39:19,079 Automation and and things like this but 1076 00:39:22,190 --> 00:39:20,820 one of the one of the really cool 1077 00:39:24,109 --> 00:39:22,200 aspects of this and there's a whole 1078 00:39:26,089 --> 00:39:24,119 Community by the way with um you know 1079 00:39:27,829 --> 00:39:26,099 people like uh Randy gallistel and Sam 1080 00:39:30,290 --> 00:39:27,839 gershman and um you know of course 1081 00:39:32,750 --> 00:39:30,300 glansman David glansman and people who 1082 00:39:34,970 --> 00:39:32,760 are that that story of memory in the in 1083 00:39:36,530 --> 00:39:34,980 the precise details of the um of the 1084 00:39:38,089 --> 00:39:36,540 synapses is that that story is really 1085 00:39:39,770 --> 00:39:38,099 starting to crack actually for a number 1086 00:39:41,329 --> 00:39:39,780 of reasons but one of the one of the 1087 00:39:43,550 --> 00:39:41,339 cool things that that was done in the 1088 00:39:46,430 --> 00:39:43,560 Russian work and it was also done later 1089 00:39:48,470 --> 00:39:46,440 on by um uh Doug Blackiston who's who's 1090 00:39:50,589 --> 00:39:48,480 in my lab now as a staff scientist and 1091 00:39:52,730 --> 00:39:50,599 other people is this this you can 1092 00:39:54,470 --> 00:39:52,740 certain certain animals that go through 1093 00:39:56,390 --> 00:39:54,480 larval stages right so you can take so 1094 00:39:58,790 --> 00:39:56,400 what the Russians were using um beetle 1095 00:40:01,190 --> 00:39:58,800 beetle larvae and uh and Doug and other 1096 00:40:03,109 --> 00:40:01,200 people used uh used used moths and 1097 00:40:05,690 --> 00:40:03,119 butterflies so what happens is you train 1098 00:40:07,550 --> 00:40:05,700 you train the larva right so so here 1099 00:40:09,109 --> 00:40:07,560 you've got a butterfly a caterpillar so 1100 00:40:10,849 --> 00:40:09,119 so this caterpillar lives in a 1101 00:40:12,290 --> 00:40:10,859 two-dimensional world it's a soft-bodied 1102 00:40:13,849 --> 00:40:12,300 robot it lives in a two-dimensional 1103 00:40:15,530 --> 00:40:13,859 world that eats leaves and so on right 1104 00:40:17,150 --> 00:40:15,540 and so you train this thing for a 1105 00:40:19,730 --> 00:40:17,160 particular task well during 1106 00:40:21,950 --> 00:40:19,740 metamorphosis it needs to become a moth 1107 00:40:23,210 --> 00:40:21,960 or butterfly which it lives in a 1108 00:40:24,770 --> 00:40:23,220 three-dimensional world plus it's a 1109 00:40:26,210 --> 00:40:24,780 hard-bodied creature so so the 1110 00:40:27,770 --> 00:40:26,220 controller is completely different right 1111 00:40:29,630 --> 00:40:27,780 for running this for running a 1112 00:40:31,550 --> 00:40:29,640 caterpillar versus a butterfly so so 1113 00:40:34,010 --> 00:40:31,560 during that process what happens is the 1114 00:40:35,450 --> 00:40:34,020 brain is basically dissolved so most of 1115 00:40:37,790 --> 00:40:35,460 the connections are broken most of the 1116 00:40:39,290 --> 00:40:37,800 cells are gone they die uh you you put 1117 00:40:41,450 --> 00:40:39,300 together a brand new brain itself 1118 00:40:43,130 --> 00:40:41,460 assembles and you can ask all sorts of 1119 00:40:44,930 --> 00:40:43,140 interesting philosophical questions of 1120 00:40:46,430 --> 00:40:44,940 what it's like to be a creature whose 1121 00:40:49,490 --> 00:40:46,440 brain is undergoing this massive change 1122 00:40:51,650 --> 00:40:49,500 uh but the information remains and and 1123 00:40:53,210 --> 00:40:51,660 so one can ask okay this is you know 1124 00:40:55,550 --> 00:40:53,220 certainly for computer science it's it's 1125 00:40:57,710 --> 00:40:55,560 amazing to have a cop to have to have a 1126 00:41:00,310 --> 00:40:57,720 memory medium that can survive this 1127 00:41:03,470 --> 00:41:00,320 radical re Remodeling and reconstruction 1128 00:41:04,730 --> 00:41:03,480 and there's there's the RNA story but 1129 00:41:06,710 --> 00:41:04,740 but also 1130 00:41:08,569 --> 00:41:06,720 um uh you had mentioned you know does 1131 00:41:10,910 --> 00:41:08,579 this does this work from for mammals so 1132 00:41:12,530 --> 00:41:10,920 there was a guy in the 70s and 80s there 1133 00:41:14,510 --> 00:41:12,540 was a there was a guy named George Ungar 1134 00:41:18,530 --> 00:41:14,520 who did tons of he's got tons of papers 1135 00:41:20,990 --> 00:41:18,540 he uh reproduced it in rats so so his 1136 00:41:23,210 --> 00:41:21,000 was fear of the dark and he actually 1137 00:41:24,170 --> 00:41:23,220 um by by establishing this essay and 1138 00:41:25,970 --> 00:41:24,180 then 1139 00:41:28,010 --> 00:41:25,980 um uh you know fractionating their 1140 00:41:30,349 --> 00:41:28,020 brains and and extracting this this 1141 00:41:32,750 --> 00:41:30,359 activity now he thought it was a peptide 1142 00:41:34,609 --> 00:41:32,760 not not RNA so he he ended up with a 1143 00:41:36,410 --> 00:41:34,619 with a thing called uh scottophobin 1144 00:41:39,230 --> 00:41:36,420 which turns out to be I think an eight 1145 00:41:40,490 --> 00:41:39,240 mer peptide or something and the claim 1146 00:41:42,770 --> 00:41:40,500 was that you can transfer this 1147 00:41:44,750 --> 00:41:42,780 scotophobia you can synthesize it and 1148 00:41:46,490 --> 00:41:44,760 then transfer it from brain to brain and 1149 00:41:47,870 --> 00:41:46,500 and that's and that's you know that's 1150 00:41:49,790 --> 00:41:47,880 that's that's what he thought it was and 1151 00:41:52,609 --> 00:41:49,800 then of course I think David glansman 1152 00:41:53,930 --> 00:41:52,619 favors RNA again but yeah I agree with 1153 00:41:56,630 --> 00:41:53,940 you I think I think that's a that's a 1154 00:41:59,150 --> 00:41:56,640 that's a super important story of how it 1155 00:42:01,910 --> 00:41:59,160 is that this kind of information can 1156 00:42:03,530 --> 00:42:01,920 survive uh just just massive uh 1157 00:42:05,870 --> 00:42:03,540 remodeling of the of the cognitive 1158 00:42:07,490 --> 00:42:05,880 substrate in planaria what we what we 1159 00:42:09,349 --> 00:42:07,500 did and and planaria you know they they 1160 00:42:11,390 --> 00:42:09,359 have a true centralized brain they have 1161 00:42:12,710 --> 00:42:11,400 all the same neurotransmitters that we 1162 00:42:14,210 --> 00:42:12,720 have they're not as simple a simple 1163 00:42:15,950 --> 00:42:14,220 organism 1164 00:42:17,930 --> 00:42:15,960 um what we did was McConnell's first 1165 00:42:19,490 --> 00:42:17,940 experiments which is to train them on 1166 00:42:22,849 --> 00:42:19,500 something and we train them to recognize 1167 00:42:24,349 --> 00:42:22,859 a laser etched um kind of bumpy pattern 1168 00:42:25,609 --> 00:42:24,359 on the bottom of the dish to recognize 1169 00:42:26,690 --> 00:42:25,619 that that's where their food was going 1170 00:42:28,970 --> 00:42:26,700 to be found so they made this 1171 00:42:30,950 --> 00:42:28,980 association between this pattern and the 1172 00:42:33,230 --> 00:42:30,960 and getting food and then we cut their 1173 00:42:34,910 --> 00:42:33,240 heads off and and we took the Tails and 1174 00:42:36,650 --> 00:42:34,920 the Tails sit there for 10 days doing 1175 00:42:38,569 --> 00:42:36,660 nothing and then eventually they grow a 1176 00:42:40,730 --> 00:42:38,579 new brain and what happens is that 1177 00:42:41,870 --> 00:42:40,740 information is then imprinted onto the 1178 00:42:44,030 --> 00:42:41,880 new brain and then and then you can 1179 00:42:46,030 --> 00:42:44,040 recover behavioral you know evidence 1180 00:42:48,829 --> 00:42:46,040 that they remember the information 1181 00:42:51,170 --> 00:42:48,839 so so that's pretty cool too because it 1182 00:42:53,569 --> 00:42:51,180 suggests that well we don't know if the 1183 00:42:55,609 --> 00:42:53,579 information is everywhere or if it's in 1184 00:42:57,290 --> 00:42:55,619 other places in the peripheral nervous 1185 00:42:58,670 --> 00:42:57,300 system or in this you know in the Nerf 1186 00:43:01,190 --> 00:42:58,680 core that we don't know where it is yet 1187 00:43:03,109 --> 00:43:01,200 but it's clear that it can move around 1188 00:43:04,910 --> 00:43:03,119 that the information can move around in 1189 00:43:06,710 --> 00:43:04,920 the body because it can be in the 1190 00:43:08,210 --> 00:43:06,720 posterior half and then imprinted onto 1191 00:43:09,650 --> 00:43:08,220 the brain which actually drives all the 1192 00:43:11,750 --> 00:43:09,660 all the behaviors 1193 00:43:13,790 --> 00:43:11,760 so thinking about that I I totally agree 1194 00:43:16,069 --> 00:43:13,800 that this is this is a really important 1195 00:43:17,750 --> 00:43:16,079 rabbit hole for asking but but it has it 1196 00:43:20,390 --> 00:43:17,760 there's an interesting puzzle here which 1197 00:43:24,190 --> 00:43:20,400 which is which is this you know it's one 1198 00:43:27,710 --> 00:43:24,200 thing to remember things that are 1199 00:43:29,210 --> 00:43:27,720 evolutionarily uh adaptive like fear of 1200 00:43:31,190 --> 00:43:29,220 the dark and things like this but 1201 00:43:33,829 --> 00:43:31,200 imagine and this hasn't really been done 1202 00:43:35,210 --> 00:43:33,839 well but imagine for a moment if we 1203 00:43:37,910 --> 00:43:35,220 could train them to something that is 1204 00:43:40,190 --> 00:43:37,920 completely novel let's say let's say we 1205 00:43:41,990 --> 00:43:40,200 train them um uh three yellow life 1206 00:43:43,430 --> 00:43:42,000 flashes means so take a step to your 1207 00:43:44,750 --> 00:43:43,440 left otherwise you get shocked something 1208 00:43:46,130 --> 00:43:44,760 like that and let's say they learn to do 1209 00:43:47,990 --> 00:43:46,140 it we haven't done this yet but let's 1210 00:43:50,690 --> 00:43:48,000 say let's say this could be could work 1211 00:43:52,609 --> 00:43:50,700 one of the big uh puzzles is going to be 1212 00:43:54,530 --> 00:43:52,619 when you extract whatever it is that you 1213 00:43:56,450 --> 00:43:54,540 extract let's say it's RNA or protein 1214 00:43:59,809 --> 00:43:56,460 whatever it is you stick it into the 1215 00:44:01,370 --> 00:43:59,819 brain of a recipient host and in order 1216 00:44:02,569 --> 00:44:01,380 for that memory to transfer one of the 1217 00:44:04,550 --> 00:44:02,579 things that the host has to be able to 1218 00:44:06,829 --> 00:44:04,560 do is has to be able to decode it in 1219 00:44:08,390 --> 00:44:06,839 order to decode it it's one thing if we 1220 00:44:10,130 --> 00:44:08,400 share the same code book and by 1221 00:44:11,569 --> 00:44:10,140 Evolution we could have this same code 1222 00:44:13,309 --> 00:44:11,579 book for things that come up all the 1223 00:44:16,490 --> 00:44:13,319 time like fear of the dark fear you know 1224 00:44:18,470 --> 00:44:16,500 things like that but how do you how how 1225 00:44:20,270 --> 00:44:18,480 would the recipient look at a a a a 1226 00:44:22,609 --> 00:44:20,280 weird sort of you know some some kind of 1227 00:44:24,230 --> 00:44:22,619 crazy hairpin RNA structure and look at 1228 00:44:27,109 --> 00:44:24,240 and and analyze it and be like oh yes 1229 00:44:28,970 --> 00:44:27,119 that's three light flashes and then uh 1230 00:44:31,550 --> 00:44:28,980 step to the left I see so you would need 1231 00:44:33,470 --> 00:44:31,560 to be able to interpret somehow this the 1232 00:44:35,210 --> 00:44:33,480 structure and convert it back to the 1233 00:44:37,970 --> 00:44:35,220 behavior and for and for behaviors that 1234 00:44:39,530 --> 00:44:37,980 are truly arbitrary that might be I I 1235 00:44:41,990 --> 00:44:39,540 don't know actually how that would work 1236 00:44:45,650 --> 00:44:42,000 and so so I think the frontier of this 1237 00:44:47,990 --> 00:44:45,660 field is going to be to have a really uh 1238 00:44:50,329 --> 00:44:48,000 convincing demonstration of of a 1239 00:44:52,670 --> 00:44:50,339 transfer of a memory that doesn't have a 1240 00:44:54,710 --> 00:44:52,680 plausible pre-existing shared 1241 00:44:56,030 --> 00:44:54,720 evolutionary decoding because because 1242 00:44:57,650 --> 00:44:56,040 otherwise you have a you have a real 1243 00:44:59,750 --> 00:44:57,660 puzzle as to how the how the the 1244 00:45:01,490 --> 00:44:59,760 decoding is going to work so this this 1245 00:45:03,410 --> 00:45:01,500 idea and and then and then even without 1246 00:45:06,230 --> 00:45:03,420 the transfer you can also think of it a 1247 00:45:08,210 --> 00:45:06,240 different way every memory is like a 1248 00:45:09,530 --> 00:45:08,220 message is like basically a transplanted 1249 00:45:11,390 --> 00:45:09,540 message from your past self to your 1250 00:45:12,710 --> 00:45:11,400 future self meaning that you still have 1251 00:45:14,510 --> 00:45:12,720 to decode your memories whatever your 1252 00:45:16,010 --> 00:45:14,520 memories are in an important sense you 1253 00:45:18,410 --> 00:45:16,020 have to you know those engrams you have 1254 00:45:20,870 --> 00:45:18,420 to decode them somehow so 1255 00:45:22,550 --> 00:45:20,880 um that that whole issue of of encoding 1256 00:45:24,230 --> 00:45:22,560 and decoding whatever the substrate of 1257 00:45:26,890 --> 00:45:24,240 memory is is you know maybe one of the 1258 00:45:29,329 --> 00:45:26,900 most important questions there are 1259 00:45:31,190 --> 00:45:29,339 one of the ways I we can think about 1260 00:45:34,630 --> 00:45:31,200 these engrams I think that there are 1261 00:45:37,430 --> 00:45:34,640 priors that condition what kinds of 1262 00:45:40,910 --> 00:45:37,440 features are being spawned in which 1263 00:45:42,589 --> 00:45:40,920 context for instance when we see a new 1264 00:45:46,309 --> 00:45:42,599 scene the way that perception seems to 1265 00:45:47,750 --> 00:45:46,319 be working is that we uh spawn lots lots 1266 00:45:49,670 --> 00:45:47,760 of feature controllers that then 1267 00:45:51,770 --> 00:45:49,680 organize into objects that are 1268 00:45:54,470 --> 00:45:51,780 controlled at the level of the scene 1269 00:45:56,870 --> 00:45:54,480 and uh this is basically a game engine 1270 00:45:59,089 --> 00:45:56,880 that is forming in our brain that is 1271 00:46:02,630 --> 00:45:59,099 creating a population of interacting 1272 00:46:04,430 --> 00:46:02,640 objects that are tuned to track our 1273 00:46:05,690 --> 00:46:04,440 perceptual data at the lowest level so 1274 00:46:09,109 --> 00:46:05,700 all the patterns that we get from our 1275 00:46:10,130 --> 00:46:09,119 retina and so on uh are samples noisy 1276 00:46:12,050 --> 00:46:10,140 samples 1277 00:46:13,609 --> 00:46:12,060 um that are difficult to interpret but 1278 00:46:15,829 --> 00:46:13,619 we are matching them into these 1279 00:46:18,290 --> 00:46:15,839 hierarchies of features that are 1280 00:46:20,750 --> 00:46:18,300 translated into objects that assign 1281 00:46:23,210 --> 00:46:20,760 every feed a feature to exactly one 1282 00:46:25,190 --> 00:46:23,220 object and every pixel so to speak to 1283 00:46:28,010 --> 00:46:25,200 exactly one except in the case of 1284 00:46:29,690 --> 00:46:28,020 transparency and use this to interpret 1285 00:46:31,370 --> 00:46:29,700 the scene that is happening in front of 1286 00:46:33,589 --> 00:46:31,380 us and when we are in the dark 1287 00:46:35,569 --> 00:46:33,599 what happens is that we spawn lots of 1288 00:46:38,030 --> 00:46:35,579 object controllers without being able to 1289 00:46:40,910 --> 00:46:38,040 disprove them because there is no data 1290 00:46:43,370 --> 00:46:40,920 that forces us to reject them and if you 1291 00:46:45,230 --> 00:46:43,380 have a vivid imagination especially as a 1292 00:46:47,329 --> 00:46:45,240 child you will feel this Darkness 1293 00:46:49,309 --> 00:46:47,339 automatically with lots of objects many 1294 00:46:52,670 --> 00:46:49,319 of which will be scary 1295 00:46:54,349 --> 00:46:52,680 and so I think that lots of the fear of 1296 00:46:56,990 --> 00:46:54,359 the dark doesn't need a lot of encoding 1297 00:46:59,569 --> 00:46:57,000 in our brain it is just an artifact of 1298 00:47:01,069 --> 00:46:59,579 the fact that there are scary things in 1299 00:47:03,230 --> 00:47:01,079 the world which I learned to represent 1300 00:47:04,849 --> 00:47:03,240 at an early age and that we cannot 1301 00:47:06,170 --> 00:47:04,859 disprove them that they just will just 1302 00:47:08,630 --> 00:47:06,180 spawn 1303 00:47:10,250 --> 00:47:08,640 I remember this vividly as a child that 1304 00:47:14,089 --> 00:47:10,260 whenever I had to go into the dark 1305 00:47:17,510 --> 00:47:14,099 basement to uh get some food in our 1306 00:47:19,370 --> 00:47:17,520 house uh in the countryside that this 1307 00:47:20,870 --> 00:47:19,380 Darkness automatically filled with all 1308 00:47:22,550 --> 00:47:20,880 sorts of shapes and things and 1309 00:47:25,970 --> 00:47:22,560 possibilities 1310 00:47:27,829 --> 00:47:25,980 and it took me later to learn that uh 1311 00:47:30,829 --> 00:47:27,839 you need to be much more afraid of the 1312 00:47:32,870 --> 00:47:30,839 ghosts that can hide in the light 1313 00:47:34,670 --> 00:47:32,880 so what would be the implications of if 1314 00:47:35,690 --> 00:47:34,680 you were able to transfer memory for 1315 00:47:37,790 --> 00:47:35,700 something that's 1316 00:47:40,550 --> 00:47:37,800 not trivial so nothing that's like an 1317 00:47:44,030 --> 00:47:40,560 archetype of fear of the dark between 1318 00:47:46,069 --> 00:47:44,040 a mammal like rats 1319 00:47:47,630 --> 00:47:46,079 and when I say transfer memory I mean in 1320 00:47:49,069 --> 00:47:47,640 this way that you blend up the brain or 1321 00:47:51,050 --> 00:47:49,079 you and also can you explain what's 1322 00:47:52,550 --> 00:47:51,060 meant by I think I understand what it 1323 00:47:53,690 --> 00:47:52,560 means to blend the brain of a planaria 1324 00:47:55,910 --> 00:47:53,700 but I don't think that's the same 1325 00:47:58,309 --> 00:47:55,920 process that's going on in rats maybe it 1326 00:48:00,290 --> 00:47:58,319 is they they well ongar did exactly the 1327 00:48:01,970 --> 00:48:00,300 same thing he would train rats for 1328 00:48:04,550 --> 00:48:01,980 particular tasks he would extract the 1329 00:48:06,829 --> 00:48:04,560 brain literally liquefy to extract the 1330 00:48:09,050 --> 00:48:06,839 chemical contents uh he would then 1331 00:48:10,609 --> 00:48:09,060 either inject the whole extract or a 1332 00:48:12,829 --> 00:48:10,619 filtered extract where you would divide 1333 00:48:14,990 --> 00:48:12,839 it up you'd fractionated so here's the 1334 00:48:17,329 --> 00:48:15,000 rnas here's the proteins here you know 1335 00:48:19,790 --> 00:48:17,339 other things uh and and then he would 1336 00:48:22,670 --> 00:48:19,800 inject that liquid directly into the 1337 00:48:25,130 --> 00:48:22,680 brains of recipient rats so you know 1338 00:48:27,349 --> 00:48:25,140 when you do that you lose you lose 1339 00:48:28,970 --> 00:48:27,359 spatial structure on the input because 1340 00:48:30,349 --> 00:48:28,980 you just Blended your brain whatever 1341 00:48:34,190 --> 00:48:30,359 spatial structure otherwise you just 1342 00:48:36,349 --> 00:48:34,200 destroyed it also on the recipient you 1343 00:48:37,910 --> 00:48:36,359 just you just inject it it's not you 1344 00:48:39,349 --> 00:48:37,920 know you're not finding that particular 1345 00:48:41,329 --> 00:48:39,359 place where you're going to stick that 1346 00:48:42,470 --> 00:48:41,339 you just inject this this thing right in 1347 00:48:44,390 --> 00:48:42,480 the middle of the brain who knows where 1348 00:48:45,770 --> 00:48:44,400 it goes you know where the fluid goes is 1349 00:48:48,890 --> 00:48:45,780 it sort of there's no spatial 1350 00:48:52,190 --> 00:48:48,900 specificity there whatsoever so if that 1351 00:48:54,290 --> 00:48:52,200 works uh what you're counting on is the 1352 00:48:57,710 --> 00:48:54,300 ability of the brain to take up 1353 00:48:59,630 --> 00:48:57,720 information via a completely novel route 1354 00:49:01,250 --> 00:48:59,640 so it's not information that's for 1355 00:49:03,470 --> 00:49:01,260 example visual right visual information 1356 00:49:05,150 --> 00:49:03,480 the accounts it comes in exactly the 1357 00:49:06,650 --> 00:49:05,160 same place all the time right there are 1358 00:49:08,210 --> 00:49:06,660 there are there are optic nerves that 1359 00:49:09,290 --> 00:49:08,220 connect to the same place in the in the 1360 00:49:12,410 --> 00:49:09,300 brain and that's where that information 1361 00:49:15,710 --> 00:49:12,420 arrives if you bathe the brain in some 1362 00:49:17,809 --> 00:49:15,720 sort of uh informational extract you're 1363 00:49:19,730 --> 00:49:17,819 basically asking the cells to take it up 1364 00:49:21,650 --> 00:49:19,740 almost as as a primitive animal would 1365 00:49:23,210 --> 00:49:21,660 with taste or touch you right that's 1366 00:49:24,710 --> 00:49:23,220 kind of distributed all over the body 1367 00:49:26,089 --> 00:49:24,720 and you can sort of pick it up anywhere 1368 00:49:28,190 --> 00:49:26,099 and then you have to process this 1369 00:49:29,690 --> 00:49:28,200 information so so you've got those 1370 00:49:31,370 --> 00:49:29,700 issues right off the bat right that 1371 00:49:33,710 --> 00:49:31,380 you've destroyed the incoming spatial 1372 00:49:35,690 --> 00:49:33,720 structure you you can't really count on 1373 00:49:38,630 --> 00:49:35,700 where it's going to land in the brain 1374 00:49:40,030 --> 00:49:38,640 and and then the third thing is as you 1375 00:49:41,990 --> 00:49:40,040 just mentioned is the idea that 1376 00:49:45,710 --> 00:49:42,000 especially if we start with information 1377 00:49:50,510 --> 00:49:45,720 that isn't any that is is that is so um 1378 00:49:51,490 --> 00:49:50,520 uh kind of uh specific and 1379 00:49:54,950 --> 00:49:51,500 um 1380 00:49:56,510 --> 00:49:54,960 you know kind of uh invented you know 1381 00:49:57,829 --> 00:49:56,520 that free light flashes means move to 1382 00:49:59,510 --> 00:49:57,839 your left I mean there's never there's 1383 00:50:01,490 --> 00:49:59,520 never been an evolutionary reason to 1384 00:50:02,930 --> 00:50:01,500 have that encoded like as you just said 1385 00:50:04,609 --> 00:50:02,940 having a fear of the dark is absolutely 1386 00:50:06,470 --> 00:50:04,619 a natural kind of thing that shows that 1387 00:50:08,030 --> 00:50:06,480 that you can expect but and then there 1388 00:50:10,430 --> 00:50:08,040 are many other things like that but but 1389 00:50:12,349 --> 00:50:10,440 something something as as contrived as 1390 00:50:13,910 --> 00:50:12,359 as you know three light flashes and then 1391 00:50:16,130 --> 00:50:13,920 you move to your left there's no reason 1392 00:50:18,349 --> 00:50:16,140 to think that we have a built-in way to 1393 00:50:20,930 --> 00:50:18,359 recognize that so when you as a as a 1394 00:50:23,150 --> 00:50:20,940 recipient brain are handed this weird uh 1395 00:50:25,430 --> 00:50:23,160 molecule with a particular structure or 1396 00:50:27,950 --> 00:50:25,440 or a set of molecules uh being able to 1397 00:50:29,809 --> 00:50:27,960 analyze that having the cells in your 1398 00:50:31,790 --> 00:50:29,819 brain or or other parts of the body 1399 00:50:34,010 --> 00:50:31,800 actually that could Analyze That and 1400 00:50:35,809 --> 00:50:34,020 recover that original information would 1401 00:50:37,910 --> 00:50:35,819 be extremely puzzling I actually don't 1402 00:50:40,130 --> 00:50:37,920 know how that would work and I'm a big 1403 00:50:41,750 --> 00:50:40,140 fan of of unlikely sounding experiments 1404 00:50:44,510 --> 00:50:41,760 that have implications if they would 1405 00:50:47,030 --> 00:50:44,520 work so this is something that uh that I 1406 00:50:48,349 --> 00:50:47,040 think should absolutely be done and um 1407 00:50:51,109 --> 00:50:48,359 and you know at some point we'll we'll 1408 00:50:52,849 --> 00:50:51,119 do it but we haven't done it yet but so 1409 00:50:55,010 --> 00:50:52,859 how far did the research in my school 1410 00:50:58,910 --> 00:50:55,020 what is the complexity of things that 1411 00:51:01,370 --> 00:50:58,920 could be transmitted via this road the I 1412 00:51:06,170 --> 00:51:01,380 as as I I don't remember everything that 1413 00:51:07,069 --> 00:51:06,180 he did uh the vast majority of he he did 1414 00:51:08,690 --> 00:51:07,079 not 1415 00:51:11,150 --> 00:51:08,700 um go 1416 00:51:12,589 --> 00:51:11,160 far to test all the complexities what he 1417 00:51:14,569 --> 00:51:12,599 tried to do was because as you can 1418 00:51:16,790 --> 00:51:14,579 imagine he faced incredible opposition 1419 00:51:18,770 --> 00:51:16,800 right so so everybody you know sort of 1420 00:51:21,770 --> 00:51:18,780 wanted to critique this thing so he 1421 00:51:23,329 --> 00:51:21,780 spent all of his time on he picked one 1422 00:51:25,670 --> 00:51:23,339 simple assay which was this fear of the 1423 00:51:28,730 --> 00:51:25,680 dark thing and then he just he just 1424 00:51:30,589 --> 00:51:28,740 bashed it for for 20 years uh to just 1425 00:51:32,690 --> 00:51:30,599 finally try to kind of crack that into 1426 00:51:34,970 --> 00:51:32,700 the into the Paradigm he did not 1427 00:51:37,309 --> 00:51:34,980 um as far as I know do lots of different 1428 00:51:39,109 --> 00:51:37,319 assays to try and make it more complex I 1429 00:51:42,109 --> 00:51:39,119 think uh I think it you know it's it's 1430 00:51:43,430 --> 00:51:42,119 very ripe for for investigation uh this 1431 00:51:44,870 --> 00:51:43,440 is the kind of did anyone else build 1432 00:51:46,609 --> 00:51:44,880 upon his work 1433 00:51:48,890 --> 00:51:46,619 um not that I know I mean I mean David 1434 00:51:50,569 --> 00:51:48,900 glansman is the best modern person who 1435 00:51:53,510 --> 00:51:50,579 works on this right so he does aplizia 1436 00:51:55,970 --> 00:51:53,520 and he you know and he does RNA so so he 1437 00:51:57,910 --> 00:51:55,980 favors um he favors RNA 1438 00:52:01,309 --> 00:51:57,920 um there's a little bit of work from um 1439 00:52:04,250 --> 00:52:01,319 in Israel with C elegans uh he's kind of 1440 00:52:06,109 --> 00:52:04,260 looking into that it uh there's related 1441 00:52:08,630 --> 00:52:06,119 work that has to do with cryogenics 1442 00:52:11,750 --> 00:52:08,640 which is this this you know this idea 1443 00:52:13,490 --> 00:52:11,760 idea that that if if it is if if 1444 00:52:16,970 --> 00:52:13,500 memories are a particular kind of 1445 00:52:18,470 --> 00:52:16,980 dynamic electrical State then some sort 1446 00:52:20,870 --> 00:52:18,480 of cryogenic freezing is probably going 1447 00:52:24,410 --> 00:52:20,880 to disrupt that whereas if it's a stable 1448 00:52:25,970 --> 00:52:24,420 molecule then it should survive so again 1449 00:52:27,890 --> 00:52:25,980 I think there are people interested in 1450 00:52:29,329 --> 00:52:27,900 that aspect of it but I'm not sure 1451 00:52:32,390 --> 00:52:29,339 um I'm not sure they've done anything 1452 00:52:35,329 --> 00:52:32,400 with it there's also a goraf uh 1453 00:52:38,569 --> 00:52:35,339 venkataraman I think he's oh yes yes 1454 00:52:40,730 --> 00:52:38,579 yeah yeah yeah yeah he uh taught me that 1455 00:52:41,990 --> 00:52:40,740 uh he has been working on this for 1456 00:52:45,349 --> 00:52:42,000 several years but he said It's 1457 00:52:47,990 --> 00:52:45,359 sociologically Tricky and that's to me 1458 00:52:51,530 --> 00:52:48,000 fascinating that we should care about 1459 00:52:53,510 --> 00:52:51,540 that what does he mean by that what do 1460 00:52:56,270 --> 00:52:53,520 you care about what stupid people think 1461 00:52:58,549 --> 00:52:56,280 uh if this uh possibility exists that 1462 00:53:01,370 --> 00:52:58,559 this works the upside is so big that 1463 00:53:03,829 --> 00:53:01,380 it's criminal to not research this I I 1464 00:53:05,450 --> 00:53:03,839 think it's a disaster that you can read 1465 00:53:07,490 --> 00:53:05,460 uh introductory textbooks on your 1466 00:53:09,710 --> 00:53:07,500 residence and never ever hear about any 1467 00:53:11,630 --> 00:53:09,720 of these experiments yeah yeah like uh 1468 00:53:13,910 --> 00:53:11,640 everybody who gets the introductory 1469 00:53:16,069 --> 00:53:13,920 stuff on Neuroscience only knows about 1470 00:53:19,910 --> 00:53:16,079 uh information stored in the connect 1471 00:53:22,910 --> 00:53:19,920 home and this leads to for instance the 1472 00:53:24,829 --> 00:53:22,920 blue brain project if that if RNA based 1473 00:53:27,589 --> 00:53:24,839 memory transfer is a thing then this 1474 00:53:29,750 --> 00:53:27,599 entire project is doomed and because you 1475 00:53:31,849 --> 00:53:29,760 cannot get the story out of uh just 1476 00:53:33,710 --> 00:53:31,859 recording the contact home or the most 1477 00:53:36,049 --> 00:53:33,720 of the research right now is focused on 1478 00:53:38,630 --> 00:53:36,059 reconstructing The Chronic tone as as it 1479 00:53:40,670 --> 00:53:38,640 was circuitry and hoping that we can get 1480 00:53:43,670 --> 00:53:40,680 the functionality of information 1481 00:53:45,950 --> 00:53:43,680 processing and to use the specificity of 1482 00:53:48,170 --> 00:53:45,960 the particular brain what it has learned 1483 00:53:50,210 --> 00:53:48,180 from the connections between neurons but 1484 00:53:53,150 --> 00:53:50,220 what if it turns out this doesn't matter 1485 00:53:55,250 --> 00:53:53,160 what is if you just need a connection 1486 00:53:56,930 --> 00:53:55,260 that dense enough and so basically 1487 00:53:59,329 --> 00:53:56,940 stochastic lattice that is somewhat 1488 00:54:00,470 --> 00:53:59,339 randomly wired and what matters is what 1489 00:54:02,030 --> 00:54:00,480 the new ones are doing with the 1490 00:54:04,130 --> 00:54:02,040 information that they're getting through 1491 00:54:05,930 --> 00:54:04,140 this ether to this lattice right this 1492 00:54:07,970 --> 00:54:05,940 changes the entire way in which we need 1493 00:54:09,530 --> 00:54:07,980 to look at things and if this 1494 00:54:11,630 --> 00:54:09,540 possibility exists and if this 1495 00:54:13,309 --> 00:54:11,640 possibility it's just one percent but 1496 00:54:16,010 --> 00:54:13,319 there is some experimentice points in 1497 00:54:17,809 --> 00:54:16,020 this direction it is not 1498 00:54:20,390 --> 00:54:17,819 um it's ridiculous to not pursue this 1499 00:54:22,130 --> 00:54:20,400 with high pressure and focus on it and 1500 00:54:25,190 --> 00:54:22,140 support research that goes in this 1501 00:54:26,870 --> 00:54:25,200 direction basically what's useful is not 1502 00:54:28,849 --> 00:54:26,880 so much answering questions in science 1503 00:54:31,370 --> 00:54:28,859 it's discovering questions it's 1504 00:54:32,990 --> 00:54:31,380 discovering new uncertainty reducing the 1505 00:54:34,609 --> 00:54:33,000 uncertainty is much easier than 1506 00:54:36,230 --> 00:54:34,619 discovering new areas of where you 1507 00:54:39,349 --> 00:54:36,240 thought that you were certain 1508 00:54:41,450 --> 00:54:39,359 but that allow you to get new insights 1509 00:54:43,609 --> 00:54:41,460 and it seems to me that a lot of 1510 00:54:45,650 --> 00:54:43,619 Neuroscience is stuck that does not 1511 00:54:48,770 --> 00:54:45,660 produce uh results that seem to 1512 00:54:50,270 --> 00:54:48,780 accumulate in an obvious way towards a 1513 00:54:53,390 --> 00:54:50,280 theory on how the brain processes 1514 00:54:56,109 --> 00:54:53,400 information yeah so the Neuroscience I 1515 00:54:58,430 --> 00:54:56,119 just don't deliver input to the 1516 00:55:00,890 --> 00:54:58,440 researchers and add the Transformer is 1517 00:55:03,410 --> 00:55:00,900 not the result of uh reading a lot of 1518 00:55:05,450 --> 00:55:03,420 Neuroscience it's really mostly the 1519 00:55:09,170 --> 00:55:05,460 result of people thinking about 1520 00:55:11,690 --> 00:55:09,180 statistics of data processing and it 1521 00:55:14,750 --> 00:55:11,700 would be great if we would focus on 1522 00:55:16,730 --> 00:55:14,760 ideas that are promising and new and 1523 00:55:19,430 --> 00:55:16,740 that have the power to shake existing 1524 00:55:21,650 --> 00:55:19,440 paradigms yeah this is you know this is 1525 00:55:24,410 --> 00:55:21,660 this is so important and it's not just 1526 00:55:26,510 --> 00:55:24,420 Neuroscience in developmental biology we 1527 00:55:27,710 --> 00:55:26,520 have exactly the same thing and and I'll 1528 00:55:29,930 --> 00:55:27,720 just give you two two very simple 1529 00:55:31,790 --> 00:55:29,940 examples of it where and I tell the 1530 00:55:33,710 --> 00:55:31,800 students when I when I give talks to 1531 00:55:36,170 --> 00:55:33,720 students I say isn't it amazing that 1532 00:55:37,970 --> 00:55:36,180 that in in your whole 1533 00:55:39,290 --> 00:55:37,980 course of biology in your developmental 1534 00:55:42,010 --> 00:55:39,300 biology textbook there's not a mention 1535 00:55:44,809 --> 00:55:42,020 of any of this because it completely um 1536 00:55:46,130 --> 00:55:44,819 uh just undermines a lot of the basic 1537 00:55:49,549 --> 00:55:46,140 assumptions so here's a couple of 1538 00:55:51,650 --> 00:55:49,559 examples one one example is that as of 1539 00:55:53,809 --> 00:55:51,660 trophic memory and deer so there are 1540 00:55:55,430 --> 00:55:53,819 species of deer that every year they 1541 00:55:56,630 --> 00:55:55,440 regenerate that you know the whole so 1542 00:55:57,890 --> 00:55:56,640 they make this antler rack on their 1543 00:56:01,549 --> 00:55:57,900 heads the whole thing falls off and then 1544 00:56:04,250 --> 00:56:01,559 it regrows the next year so these two 1545 00:56:05,990 --> 00:56:04,260 guys bubenic which are the Father and 1546 00:56:08,270 --> 00:56:06,000 Son team that did these experiments for 1547 00:56:09,950 --> 00:56:08,280 40 years and actually have all these 1548 00:56:12,950 --> 00:56:09,960 antlers in my lab now because when when 1549 00:56:14,329 --> 00:56:12,960 the younger one retired I asked he sent 1550 00:56:16,910 --> 00:56:14,339 me all these things all these antlers 1551 00:56:19,190 --> 00:56:16,920 the idea is this um what you can do is 1552 00:56:21,710 --> 00:56:19,200 you take a knife and somewhere in this 1553 00:56:23,870 --> 00:56:21,720 Branch structure you you make a wound 1554 00:56:25,130 --> 00:56:23,880 and the bone will heal and you get a 1555 00:56:26,750 --> 00:56:25,140 little callous and that's you know 1556 00:56:30,049 --> 00:56:26,760 that's it for that year then the whole 1557 00:56:31,849 --> 00:56:30,059 thing drops off and then next year 1558 00:56:34,069 --> 00:56:31,859 it starts to grow and it will make an 1559 00:56:36,410 --> 00:56:34,079 ectopic tine an ectopic Branch at the 1560 00:56:38,150 --> 00:56:36,420 point where you injured it last year and 1561 00:56:40,430 --> 00:56:38,160 this goes on for five or six years and 1562 00:56:43,130 --> 00:56:40,440 then eventually it goes away and and and 1563 00:56:45,770 --> 00:56:43,140 you get a normal normal rack again and 1564 00:56:47,990 --> 00:56:45,780 so the the amazing thing about it is 1565 00:56:50,270 --> 00:56:48,000 that you know as you you could you can 1566 00:56:52,370 --> 00:56:50,280 you can the the the standard models for 1567 00:56:53,990 --> 00:56:52,380 for patterning for morphogenesis are 1568 00:56:56,510 --> 00:56:54,000 these kind of um Gene regulatory 1569 00:56:58,730 --> 00:56:56,520 networks and and you know genetic um 1570 00:57:00,829 --> 00:56:58,740 Kinds of Kinds of uh biochemical 1571 00:57:02,809 --> 00:57:00,839 gradients and so on you know if you try 1572 00:57:05,750 --> 00:57:02,819 to try to come up with a with a with a 1573 00:57:07,190 --> 00:57:05,760 model for this so for for encoding an 1574 00:57:09,410 --> 00:57:07,200 arbitrary Point within a branch 1575 00:57:11,569 --> 00:57:09,420 structure that your cells at the scalp 1576 00:57:13,849 --> 00:57:11,579 have to remember for months after the 1577 00:57:15,650 --> 00:57:13,859 whole thing is dropped off and then not 1578 00:57:17,150 --> 00:57:15,660 only remember it but then implement it 1579 00:57:19,130 --> 00:57:17,160 so that when the bone starts to grow 1580 00:57:20,809 --> 00:57:19,140 something says oh yes that's the you 1581 00:57:22,549 --> 00:57:20,819 know the start another another time 1582 00:57:24,710 --> 00:57:22,559 growing to your left exactly exactly 1583 00:57:26,390 --> 00:57:24,720 here right trying to trying to make a 1584 00:57:29,510 --> 00:57:26,400 model of this using the standard tools 1585 00:57:31,010 --> 00:57:29,520 of the field is uh just just incredibly 1586 00:57:32,510 --> 00:57:31,020 difficult and and this is that that's 1587 00:57:33,790 --> 00:57:32,520 and there are other examples of this but 1588 00:57:35,750 --> 00:57:33,800 this kind of 1589 00:57:37,190 --> 00:57:35,760 non-non-genetic memory that's just very 1590 00:57:39,109 --> 00:57:37,200 difficult to explain with standard 1591 00:57:41,030 --> 00:57:39,119 models the other thing which is any I 1592 00:57:43,309 --> 00:57:41,040 think an even bigger Scandal is the 1593 00:57:43,970 --> 00:57:43,319 whole situation with planaria 1594 00:57:46,010 --> 00:57:43,980 um 1595 00:57:47,690 --> 00:57:46,020 planaria some species of planaria the 1596 00:57:49,670 --> 00:57:47,700 way they reproduce is they tear 1597 00:57:51,170 --> 00:57:49,680 themselves in half each half regenerates 1598 00:57:52,849 --> 00:57:51,180 the missing piece and now you've got two 1599 00:57:54,290 --> 00:57:52,859 that's how they reproduce so if you're 1600 00:57:56,930 --> 00:57:54,300 going to do that what you end up 1601 00:57:58,670 --> 00:57:56,940 avoiding is weissman's barrier this idea 1602 00:58:00,049 --> 00:57:58,680 that when we get mutations in our body 1603 00:58:02,390 --> 00:58:00,059 our children don't inherit those 1604 00:58:04,370 --> 00:58:02,400 mutations right so this means that any 1605 00:58:06,530 --> 00:58:04,380 mutation that doesn't kill the stem cell 1606 00:58:08,690 --> 00:58:06,540 in the body gets Amplified as that cell 1607 00:58:11,089 --> 00:58:08,700 contributes to regrowing the worm so 1608 00:58:12,530 --> 00:58:11,099 every as a result of this for for 400 1609 00:58:14,690 --> 00:58:12,540 million years these planaria have 1610 00:58:16,849 --> 00:58:14,700 accumulative mutations their genomes are 1611 00:58:18,890 --> 00:58:16,859 an incredible mess their cells are 1612 00:58:20,329 --> 00:58:18,900 basically mixoploid that meaning meaning 1613 00:58:21,410 --> 00:58:20,339 they're like a tumor every cell has a 1614 00:58:23,210 --> 00:58:21,420 different number of chromosomes 1615 00:58:25,490 --> 00:58:23,220 potentially they just they just look 1616 00:58:27,589 --> 00:58:25,500 look you know it just looks horrible as 1617 00:58:30,349 --> 00:58:27,599 an end result you've got an animal that 1618 00:58:33,349 --> 00:58:30,359 is Immortal incredibly good at 1619 00:58:36,410 --> 00:58:33,359 regenerating with 100 Fidelity and very 1620 00:58:37,970 --> 00:58:36,420 resistant to cancer now this is all of 1621 00:58:40,490 --> 00:58:37,980 this is the exact opposite of the 1622 00:58:42,109 --> 00:58:40,500 message you get uh from from from a 1623 00:58:43,730 --> 00:58:42,119 typical course through through biology 1624 00:58:45,829 --> 00:58:43,740 which it says that what is the genome 1625 00:58:47,569 --> 00:58:45,839 for The genome is for setting your body 1626 00:58:50,030 --> 00:58:47,579 structure if you mess with the genome 1627 00:58:52,309 --> 00:58:50,040 that information goes away you get you 1628 00:58:54,109 --> 00:58:52,319 get aging you get cancer right why does 1629 00:58:57,109 --> 00:58:54,119 the animal with the worst genome have 1630 00:58:58,490 --> 00:58:57,119 the the the best anatomical Fidelity I 1631 00:59:00,049 --> 00:58:58,500 mean that's just that and and I think we 1632 00:59:01,370 --> 00:59:00,059 actually as of as of you know a few 1633 00:59:03,349 --> 00:59:01,380 months ago we actually I think have some 1634 00:59:05,390 --> 00:59:03,359 insight into this but but but it's been 1635 00:59:07,309 --> 00:59:05,400 bugging me for for years and this is the 1636 00:59:09,589 --> 00:59:07,319 kind of thing that nobody ever talks 1637 00:59:11,089 --> 00:59:09,599 about because it it goes against the 1638 00:59:13,309 --> 00:59:11,099 general Assumption of what of what 1639 00:59:14,930 --> 00:59:13,319 genomes actually do and and what they're 1640 00:59:17,390 --> 00:59:14,940 for and you know this this complete lack 1641 00:59:18,770 --> 00:59:17,400 of uh correlation between the genome in 1642 00:59:20,930 --> 00:59:18,780 fact an anti-correlation between the 1643 00:59:23,270 --> 00:59:20,940 genome quality and the incredible 1644 00:59:25,730 --> 00:59:23,280 ability of this of this animal to uh to 1645 00:59:27,230 --> 00:59:25,740 to to to to have a healthy Anatomy yeah 1646 00:59:28,609 --> 00:59:27,240 what is that Insight that you mentioned 1647 00:59:31,609 --> 00:59:28,619 you acquired a few months ago 1648 00:59:33,650 --> 00:59:31,619 preliminary so so okay uh in the in the 1649 00:59:35,510 --> 00:59:33,660 name of uh you know throwing out uh kind 1650 00:59:37,670 --> 00:59:35,520 of new unproven ideas right so this is 1651 00:59:39,770 --> 00:59:37,680 you know this this is this is just my my 1652 00:59:41,270 --> 00:59:39,780 conjecture we've we've done some we've 1653 00:59:44,630 --> 00:59:41,280 done some computational modeling of it 1654 00:59:46,730 --> 00:59:44,640 which which I initially this was a um a 1655 00:59:49,010 --> 00:59:46,740 very uh clever student that I work with 1656 00:59:52,010 --> 00:59:49,020 named lakshman who I did did some models 1657 00:59:53,510 --> 00:59:52,020 with me and uh uh I initially thought it 1658 00:59:55,250 --> 00:59:53,520 was a bug and then I realized that no 1659 00:59:58,430 --> 00:59:55,260 actually this is this is this is the 1660 01:00:00,230 --> 00:59:58,440 feature the idea is this imagine so so 1661 01:00:02,630 --> 01:00:00,240 we've been working for a long a long 1662 01:00:05,270 --> 01:00:02,640 time on a concept of 1663 01:00:07,010 --> 01:00:05,280 um competency among embryonic parts and 1664 01:00:10,430 --> 01:00:07,020 what this means is basically the idea 1665 01:00:13,789 --> 01:00:10,440 that uh there are there are um 1666 01:00:16,190 --> 01:00:13,799 homeostatic feedback loops among various 1667 01:00:19,069 --> 01:00:16,200 cells and tissues and organs that 1668 01:00:21,049 --> 01:00:19,079 attempt to reach specific outcomes in 1669 01:00:23,210 --> 01:00:21,059 anatomical amorphous space despite 1670 01:00:25,190 --> 01:00:23,220 various perturbations so the idea is 1671 01:00:27,890 --> 01:00:25,200 that if you have a tadpole and you do 1672 01:00:29,569 --> 01:00:27,900 something to it whether by a mutation or 1673 01:00:31,430 --> 01:00:29,579 by a drug or something you do something 1674 01:00:33,530 --> 01:00:31,440 to it where the eye is a little 1675 01:00:35,750 --> 01:00:33,540 off-kilter or the mouth is a little off 1676 01:00:37,010 --> 01:00:35,760 all of these organs pretty much know 1677 01:00:39,109 --> 01:00:37,020 where they're supposed to be they will 1678 01:00:41,270 --> 01:00:39,119 try to minimize distance from other um 1679 01:00:42,829 --> 01:00:41,280 landmarks and they will Remodel and 1680 01:00:44,930 --> 01:00:42,839 eventually you get a normal frog so that 1681 01:00:48,230 --> 01:00:44,940 so that they will they will sort of 1682 01:00:49,789 --> 01:00:48,240 um a a recover the correct uh Anatomy 1683 01:00:51,589 --> 01:00:49,799 despite starting off in the wrong 1684 01:00:53,450 --> 01:00:51,599 position or even things like changes in 1685 01:00:55,130 --> 01:00:53,460 the number of cells or the size of cells 1686 01:00:58,069 --> 01:00:55,140 they're really good at getting their job 1687 01:00:59,809 --> 01:00:58,079 done despite various changes right so 1688 01:01:02,329 --> 01:00:59,819 okay so they have these competencies to 1689 01:01:04,490 --> 01:01:02,339 optimize specific uh things like like 1690 01:01:05,270 --> 01:01:04,500 their position and structure and things 1691 01:01:07,549 --> 01:01:05,280 like that 1692 01:01:09,109 --> 01:01:07,559 so uh so so that's so that's competency 1693 01:01:09,829 --> 01:01:09,119 now now here's here's the interesting 1694 01:01:13,970 --> 01:01:09,839 thing 1695 01:01:16,490 --> 01:01:13,980 imagine that you have a species that uh 1696 01:01:18,589 --> 01:01:16,500 has some some degree of that competency 1697 01:01:21,170 --> 01:01:18,599 and so you've got an individual of that 1698 01:01:23,390 --> 01:01:21,180 species comes up for selection uh 1699 01:01:25,190 --> 01:01:23,400 Fitness is high looks pretty good but 1700 01:01:27,530 --> 01:01:25,200 here's the problem selection doesn't 1701 01:01:30,470 --> 01:01:27,540 know whether the fitness is high because 1702 01:01:31,970 --> 01:01:30,480 his genome was amazing or the fitness is 1703 01:01:34,069 --> 01:01:31,980 high because the genome was actually so 1704 01:01:35,450 --> 01:01:34,079 so but the competency sort of made up 1705 01:01:38,030 --> 01:01:35,460 for it and now everything kind of got 1706 01:01:40,849 --> 01:01:38,040 back to where it needs to go so what the 1707 01:01:43,670 --> 01:01:40,859 competency apparently does is Shield 1708 01:01:45,710 --> 01:01:43,680 information from Evolution about the 1709 01:01:47,630 --> 01:01:45,720 actual genome it makes it harder to pick 1710 01:01:49,730 --> 01:01:47,640 the best genomes because you're 1711 01:01:51,829 --> 01:01:49,740 individuals that perform well don't 1712 01:01:55,069 --> 01:01:51,839 necessarily have the best genomes what 1713 01:01:56,450 --> 01:01:55,079 they do have is competency so what 1714 01:01:59,210 --> 01:01:56,460 happens and what happens in our 1715 01:02:00,650 --> 01:01:59,220 simulations is that when if you start 1716 01:02:04,370 --> 01:02:00,660 off with even a little bit of that 1717 01:02:06,829 --> 01:02:04,380 competency Evolution loses some power in 1718 01:02:08,390 --> 01:02:06,839 selecting the best genomes but it but 1719 01:02:10,190 --> 01:02:08,400 but where all the work tends to happen 1720 01:02:12,349 --> 01:02:10,200 is increasing the competency 1721 01:02:14,089 --> 01:02:12,359 so then the competency goes up so the 1722 01:02:15,530 --> 01:02:14,099 cells are even better at and the tissues 1723 01:02:18,470 --> 01:02:15,540 are even better at getting the job done 1724 01:02:20,930 --> 01:02:18,480 despite the bad genome that makes it 1725 01:02:23,089 --> 01:02:20,940 even worse that that that that that that 1726 01:02:25,069 --> 01:02:23,099 makes it even harder for for evolution 1727 01:02:26,809 --> 01:02:25,079 to see the best genomes which relieves 1728 01:02:29,210 --> 01:02:26,819 some of the pressure on having a good 1729 01:02:31,250 --> 01:02:29,220 genome but it basically puts all the 1730 01:02:32,870 --> 01:02:31,260 pressure on being really competent so 1731 01:02:36,349 --> 01:02:32,880 you've got this so so basically what 1732 01:02:39,109 --> 01:02:36,359 happens is that uh the the the genetic 1733 01:02:41,270 --> 01:02:39,119 fitness basically levels out at a really 1734 01:02:43,250 --> 01:02:41,280 sub-optimal level and in fact the 1735 01:02:45,770 --> 01:02:43,260 pressure is off of it so so it's 1736 01:02:47,450 --> 01:02:45,780 tolerant all kinds of craziness but the 1737 01:02:49,789 --> 01:02:47,460 competency and the mechanisms of 1738 01:02:53,030 --> 01:02:49,799 Competency get get pushed up really high 1739 01:02:54,410 --> 01:02:53,040 so in many animals and but there are 1740 01:02:56,270 --> 01:02:54,420 other factors that sort of push against 1741 01:02:57,710 --> 01:02:56,280 this ratchet but it becomes it becomes a 1742 01:03:00,650 --> 01:02:57,720 positive feedback loop it becomes a 1743 01:03:03,650 --> 01:03:00,660 ratchet for Optimal Performance despite 1744 01:03:06,470 --> 01:03:03,660 a sub-optimal genome and so in some 1745 01:03:07,549 --> 01:03:06,480 animals this sort of evens out at a 1746 01:03:10,130 --> 01:03:07,559 particular point but I think what 1747 01:03:12,349 --> 01:03:10,140 happened in planaria is that this whole 1748 01:03:14,930 --> 01:03:12,359 process ran away to its ultimate 1749 01:03:17,870 --> 01:03:14,940 conclusion the ultimate conclusion is 1750 01:03:20,390 --> 01:03:17,880 the competency algorithm became so good 1751 01:03:22,430 --> 01:03:20,400 that basically whatever the genome is 1752 01:03:24,829 --> 01:03:22,440 it's really good at creating and 1753 01:03:27,049 --> 01:03:24,839 maintaining a proper worm because it is 1754 01:03:28,970 --> 01:03:27,059 already being evolved in the presence of 1755 01:03:31,849 --> 01:03:28,980 a genome whose quality we cannot control 1756 01:03:33,829 --> 01:03:31,859 so so in computer science speak it's 1757 01:03:35,870 --> 01:03:33,839 kind of like um and Steve Frank put me 1758 01:03:37,670 --> 01:03:35,880 onto this analogy it's kind of like what 1759 01:03:40,130 --> 01:03:37,680 happens in raid arrays when you have a 1760 01:03:41,990 --> 01:03:40,140 nice raid array where the software makes 1761 01:03:44,150 --> 01:03:42,000 sure that you don't lose any data the 1762 01:03:47,210 --> 01:03:44,160 pressure is off to have really uh really 1763 01:03:48,950 --> 01:03:47,220 high quality media and so now you can 1764 01:03:50,450 --> 01:03:48,960 tolerate you can tolerate media with 1765 01:03:52,309 --> 01:03:50,460 lots of mistakes because because the 1766 01:03:54,589 --> 01:03:52,319 software takes care of it in the in the 1767 01:03:56,750 --> 01:03:54,599 raid and the on the architecture takes 1768 01:03:59,210 --> 01:03:56,760 care of it so so basically what happens 1769 01:04:02,150 --> 01:03:59,220 is you've got this animal where that uh 1770 01:04:05,270 --> 01:04:02,160 that runaway uh feedback loop went went 1771 01:04:08,510 --> 01:04:05,280 so far that the algorithm is amazing and 1772 01:04:10,309 --> 01:04:08,520 it's been it's been uh evolved 1773 01:04:12,589 --> 01:04:10,319 specifically for the ability to do what 1774 01:04:15,349 --> 01:04:12,599 it needs to do even though the hardware 1775 01:04:16,970 --> 01:04:15,359 is kind of crap and and it's it's 1776 01:04:18,710 --> 01:04:16,980 incredibly tolerant so this has a number 1777 01:04:19,789 --> 01:04:18,720 of implications that that to my 1778 01:04:22,849 --> 01:04:19,799 knowledge have never been explained 1779 01:04:24,829 --> 01:04:22,859 before for example in every kind every 1780 01:04:26,329 --> 01:04:24,839 other kind of animal you can you can 1781 01:04:28,789 --> 01:04:26,339 call a stock Center and you can get 1782 01:04:31,549 --> 01:04:28,799 mutants so you can get mice with with 1783 01:04:34,309 --> 01:04:31,559 kinky kind of Kink tails you can get 1784 01:04:36,289 --> 01:04:34,319 flies with red eyes and you can get uh 1785 01:04:38,329 --> 01:04:36,299 chickens without toes and you can get 1786 01:04:40,010 --> 01:04:38,339 you know humans come with that it has 1787 01:04:41,030 --> 01:04:40,020 various you know albinos and things you 1788 01:04:43,809 --> 01:04:41,040 can you can there's there's always 1789 01:04:47,150 --> 01:04:43,819 mutants that you can get uh planaria 1790 01:04:49,309 --> 01:04:47,160 there are no there are no abnormal lines 1791 01:04:51,349 --> 01:04:49,319 of planaria anywhere except for the only 1792 01:04:52,910 --> 01:04:51,359 exception is our two-headed line and 1793 01:04:55,730 --> 01:04:52,920 that that one's not genetic that one's 1794 01:04:57,770 --> 01:04:55,740 that one's bioelectric so so isn't it 1795 01:04:59,630 --> 01:04:57,780 amazing that that that nobody has been 1796 01:05:01,549 --> 01:04:59,640 able despite despite a hundred and you 1797 01:05:03,589 --> 01:05:01,559 know I don't know 120 years of 1798 01:05:07,010 --> 01:05:03,599 experiments with planaria nobody has 1799 01:05:08,690 --> 01:05:07,020 isolated a uh a line of planaria that is 1800 01:05:10,430 --> 01:05:08,700 anything other than a perfect planarian 1801 01:05:12,650 --> 01:05:10,440 I think this is why I think it's because 1802 01:05:13,910 --> 01:05:12,660 they have been actually selected for 1803 01:05:15,470 --> 01:05:13,920 being able to do what they need to do 1804 01:05:18,950 --> 01:05:15,480 despite the fact that there the the 1805 01:05:20,450 --> 01:05:18,960 hardware is just very junky and so so 1806 01:05:22,549 --> 01:05:20,460 that's my that's my current that's my 1807 01:05:26,270 --> 01:05:22,559 current current take on it and and and 1808 01:05:28,670 --> 01:05:26,280 really uh it puts more kind of more 1809 01:05:30,770 --> 01:05:28,680 emphasis on on on the algorithm and the 1810 01:05:33,170 --> 01:05:30,780 decision making among that cellular 1811 01:05:34,250 --> 01:05:33,180 Collective of what what you know what 1812 01:05:35,809 --> 01:05:34,260 are we going to build and what's the 1813 01:05:38,329 --> 01:05:35,819 algorithm for for making sure that we're 1814 01:05:40,010 --> 01:05:38,339 all working to build the correct thing 1815 01:05:42,710 --> 01:05:40,020 so if you translate this idea into 1816 01:05:45,230 --> 01:05:42,720 computer science a way to look at it is 1817 01:05:47,329 --> 01:05:45,240 imagine that you find some computers 1818 01:05:50,930 --> 01:05:47,339 that have 1819 01:05:52,730 --> 01:05:50,940 um artists that are very very noisy and 1820 01:05:54,349 --> 01:05:52,740 where the heart is basically makes lots 1821 01:05:57,109 --> 01:05:54,359 and lots of mistakes in encoding things 1822 01:05:58,910 --> 01:05:57,119 and bits often flip and so on and you 1823 01:06:00,950 --> 01:05:58,920 will find that these computers still 1824 01:06:02,750 --> 01:06:00,960 work and they work on pretty much the 1825 01:06:06,109 --> 01:06:02,760 same way as the other computers that you 1826 01:06:08,210 --> 01:06:06,119 have and there is an orthodox sect of 1827 01:06:10,430 --> 01:06:08,220 computer scientists that thinks uh it is 1828 01:06:13,370 --> 01:06:10,440 necessary that uh the every bit on the 1829 01:06:15,289 --> 01:06:13,380 hard disk is completely reliable or 1830 01:06:17,990 --> 01:06:15,299 reliable to such a degree that you only 1831 01:06:20,809 --> 01:06:18,000 have a mistake once every 100 trillion 1832 01:06:22,069 --> 01:06:20,819 copies and you can have an error 1833 01:06:23,750 --> 01:06:22,079 correction quote running on the hard 1834 01:06:25,549 --> 01:06:23,760 disk at the low level that corrects this 1835 01:06:27,170 --> 01:06:25,559 and after some point it doesn't become 1836 01:06:29,029 --> 01:06:27,180 efficient anymore so you need to have 1837 01:06:31,910 --> 01:06:29,039 reliable hard disks to be able to have 1838 01:06:34,130 --> 01:06:31,920 computers that work like this but uh how 1839 01:06:36,230 --> 01:06:34,140 would these other computers work and it 1840 01:06:38,329 --> 01:06:36,240 basically means that you create a 1841 01:06:40,430 --> 01:06:38,339 virtual structure on top of the noisy 1842 01:06:43,430 --> 01:06:40,440 structure that is correcting for 1843 01:06:45,230 --> 01:06:43,440 whatever degree of um uncertainty you 1844 01:06:48,410 --> 01:06:45,240 have or the degree of Randomness that 1845 01:06:51,109 --> 01:06:48,420 gets injected into your substrate David 1846 01:06:55,549 --> 01:06:51,119 Dave Eckley has a very nice metaphor for 1847 01:06:58,370 --> 01:06:55,559 this you know maybe yeah yeah he's a I 1848 01:07:00,349 --> 01:06:58,380 think a beautiful artist who explores 1849 01:07:02,390 --> 01:07:00,359 complexity by tinkering with 1850 01:07:04,670 --> 01:07:02,400 computational models I really find this 1851 01:07:06,950 --> 01:07:04,680 work very inspiring and he has this idea 1852 01:07:09,529 --> 01:07:06,960 of best effort Computing so in his view 1853 01:07:11,569 --> 01:07:09,539 our own nervous system is a best effort 1854 01:07:13,730 --> 01:07:11,579 computer it's one that does not rely on 1855 01:07:17,329 --> 01:07:13,740 the other neurons around you working 1856 01:07:20,210 --> 01:07:17,339 perfectly uh but make an effort to be 1857 01:07:22,309 --> 01:07:20,220 better than random and then you stack 1858 01:07:25,309 --> 01:07:22,319 the improbabilities empirically by 1859 01:07:28,970 --> 01:07:25,319 having a system that evolves to measure 1860 01:07:31,190 --> 01:07:28,980 in effect the unreliability of its 1861 01:07:32,990 --> 01:07:31,200 components and then stack the 1862 01:07:35,089 --> 01:07:33,000 probabilities until you get the system 1863 01:07:36,829 --> 01:07:35,099 to be deterministic enough to do what 1864 01:07:40,069 --> 01:07:36,839 you're doing with what to do with it 1865 01:07:42,770 --> 01:07:40,079 right so you uh if you have a system 1866 01:07:45,349 --> 01:07:42,780 that is as in a planaria inherently very 1867 01:07:47,750 --> 01:07:45,359 noisy where the genome is an unreliable 1868 01:07:50,750 --> 01:07:47,760 witness of what should be done and the 1869 01:07:52,789 --> 01:07:50,760 body you just need to interpret it in a 1870 01:07:55,190 --> 01:07:52,799 way that Stacks the probabilities that 1871 01:07:58,069 --> 01:07:55,200 is evaluating things with much more 1872 01:08:00,349 --> 01:07:58,079 error tolerance and maybe this is always 1873 01:08:02,150 --> 01:08:00,359 the case maybe there is a Continuum 1874 01:08:03,950 --> 01:08:02,160 um maybe not it's also possible that 1875 01:08:06,650 --> 01:08:03,960 there is some kind of phase shift where 1876 01:08:08,690 --> 01:08:06,660 your switch from organisms with reliable 1877 01:08:10,069 --> 01:08:08,700 genomes to organisms with noisy genomes 1878 01:08:11,450 --> 01:08:10,079 and you would basically use a completely 1879 01:08:13,789 --> 01:08:11,460 different way to construct the organism 1880 01:08:16,130 --> 01:08:13,799 as a result but it's a it's a very 1881 01:08:18,829 --> 01:08:16,140 interesting hypothesis then to see if if 1882 01:08:20,450 --> 01:08:18,839 this is a radical thing or a gradual 1883 01:08:23,030 --> 01:08:20,460 thing that happens on all organisms to 1884 01:08:25,070 --> 01:08:23,040 some degree yeah what I also like about 1885 01:08:28,130 --> 01:08:25,080 this uh description that you give about 1886 01:08:31,070 --> 01:08:28,140 how the organism emerges it maps on in 1887 01:08:34,430 --> 01:08:31,080 some sense also in how perception Works 1888 01:08:35,749 --> 01:08:34,440 in in our own mind at the moment measure 1889 01:08:37,610 --> 01:08:35,759 learning is mostly focused on 1890 01:08:40,669 --> 01:08:37,620 recognizing images 1891 01:08:42,709 --> 01:08:40,679 so our individual frames and the you 1892 01:08:44,090 --> 01:08:42,719 feed in information frame by frame and 1893 01:08:47,209 --> 01:08:44,100 the information is relatively 1894 01:08:49,550 --> 01:08:47,219 disconnected from a system like Delhi 2 1895 01:08:51,110 --> 01:08:49,560 is trained by giving it several hundreds 1896 01:08:52,789 --> 01:08:51,120 of millions of images 1897 01:08:54,530 --> 01:08:52,799 and they are disconnected the they're 1898 01:08:56,870 --> 01:08:54,540 not adjacent images in the space of 1899 01:08:59,390 --> 01:08:56,880 images and a baby could not probably 1900 01:09:01,309 --> 01:08:59,400 learn from giving 600 million images in 1901 01:09:02,689 --> 01:09:01,319 a dark room and only looking at this 1902 01:09:05,510 --> 01:09:02,699 introduce the structure of the world 1903 01:09:07,370 --> 01:09:05,520 from this whereas Delhi can which gives 1904 01:09:09,769 --> 01:09:07,380 Testament to the power of our 1905 01:09:11,749 --> 01:09:09,779 statistical methods and Hardware that we 1906 01:09:14,030 --> 01:09:11,759 have that far surpasses I think the 1907 01:09:15,289 --> 01:09:14,040 combined power and valuability of brains 1908 01:09:17,150 --> 01:09:15,299 which probably would not be able to 1909 01:09:18,289 --> 01:09:17,160 integrate so much information over such 1910 01:09:20,269 --> 01:09:18,299 a big distance 1911 01:09:22,729 --> 01:09:20,279 for us the world is learnable because 1912 01:09:25,309 --> 01:09:22,739 it's adjacent frames are correlated 1913 01:09:28,010 --> 01:09:25,319 basically information gets preserved in 1914 01:09:29,269 --> 01:09:28,020 the world so time and we only need to 1915 01:09:31,130 --> 01:09:29,279 learn the way in which the information 1916 01:09:33,349 --> 01:09:31,140 gets transmogorified 1917 01:09:34,910 --> 01:09:33,359 and these transformifications of 1918 01:09:37,010 --> 01:09:34,920 information means that we have a dynamic 1919 01:09:38,689 --> 01:09:37,020 World in which the static image is an 1920 01:09:40,849 --> 01:09:38,699 exception the identity function is a 1921 01:09:43,849 --> 01:09:40,859 special case of how the universe changes 1922 01:09:46,189 --> 01:09:43,859 and we mostly learn change we just got 1923 01:09:48,289 --> 01:09:46,199 visited by my cat and my cat has 1924 01:09:49,910 --> 01:09:48,299 difficulty to recognize static objects 1925 01:09:51,829 --> 01:09:49,920 compared to moving objects where it's 1926 01:09:54,229 --> 01:09:51,839 much much easier to see a moving ball 1927 01:09:55,850 --> 01:09:54,239 than a ball that is laying still yeah 1928 01:09:57,530 --> 01:09:55,860 and it's because it's much easier to 1929 01:10:00,290 --> 01:09:57,540 segment it out the environment when it 1930 01:10:01,910 --> 01:10:00,300 moves right so the task of learning on a 1931 01:10:03,890 --> 01:10:01,920 moving environmental Dynamic environment 1932 01:10:06,709 --> 01:10:03,900 is much easier because it imposes 1933 01:10:09,290 --> 01:10:06,719 constraints on the world and so how do 1934 01:10:11,570 --> 01:10:09,300 we represent a moving world compared to 1935 01:10:14,450 --> 01:10:11,580 a static well the semantics of features 1936 01:10:16,250 --> 01:10:14,460 changes and the uh an object is 1937 01:10:18,709 --> 01:10:16,260 basically composed of features that are 1938 01:10:21,169 --> 01:10:18,719 there can be objects themselves and the 1939 01:10:23,930 --> 01:10:21,179 scene is the decomposition of all the 1940 01:10:25,850 --> 01:10:23,940 features that we see into a complete set 1941 01:10:27,410 --> 01:10:25,860 of objects that explain the entirety of 1942 01:10:29,030 --> 01:10:27,420 the scene and the interaction between 1943 01:10:32,450 --> 01:10:29,040 them and causality is the interaction 1944 01:10:33,950 --> 01:10:32,460 between objects right and in a static 1945 01:10:35,510 --> 01:10:33,960 image these objects don't do anything 1946 01:10:37,130 --> 01:10:35,520 they don't interact with each other they 1947 01:10:38,870 --> 01:10:37,140 just stand in some kind of relationship 1948 01:10:40,610 --> 01:10:38,880 that you need to infer which is super 1949 01:10:43,729 --> 01:10:40,620 difficult because you only have this 1950 01:10:46,250 --> 01:10:43,739 static snapshot and so the features are 1951 01:10:48,890 --> 01:10:46,260 classifiers that tell you how to whether 1952 01:10:52,490 --> 01:10:48,900 a feature is a hand or a foot or a pen 1953 01:10:54,950 --> 01:10:52,500 or a Sun or a flashlight or whatever and 1954 01:10:56,209 --> 01:10:54,960 how they relate to the larger scene in 1955 01:10:57,590 --> 01:10:56,219 which again you have a static 1956 01:10:59,450 --> 01:10:57,600 relationship in which you need to 1957 01:11:01,490 --> 01:10:59,460 classify the objects based on the 1958 01:11:02,870 --> 01:11:01,500 features that contribute to them and you 1959 01:11:04,490 --> 01:11:02,880 need to find some kind of description 1960 01:11:05,930 --> 01:11:04,500 where you interpret the features which 1961 01:11:07,610 --> 01:11:05,940 are usually ambiguous and could be many 1962 01:11:09,350 --> 01:11:07,620 different things depending on the 1963 01:11:11,510 --> 01:11:09,360 context which you interpret them into 1964 01:11:14,450 --> 01:11:11,520 one optimal Global configuration right 1965 01:11:16,790 --> 01:11:14,460 but if scene is moving this changes a 1966 01:11:18,530 --> 01:11:16,800 little bit what happens now is that the 1967 01:11:20,689 --> 01:11:18,540 features become operators they're no 1968 01:11:22,669 --> 01:11:20,699 longer classifiers that tell you how 1969 01:11:24,050 --> 01:11:22,679 your internal State needs to change how 1970 01:11:25,669 --> 01:11:24,060 your world needs to change or your 1971 01:11:27,709 --> 01:11:25,679 simulation of the universe in your mind 1972 01:11:30,709 --> 01:11:27,719 needs to change to track the sensory 1973 01:11:33,350 --> 01:11:30,719 patterns right so a feature now is an 1974 01:11:36,110 --> 01:11:33,360 change operator a transformation 1975 01:11:38,270 --> 01:11:36,120 and uh the feature is in some sense a 1976 01:11:39,830 --> 01:11:38,280 controller that tells you how the bits 1977 01:11:42,649 --> 01:11:39,840 are moving and in your local model of 1978 01:11:44,930 --> 01:11:42,659 the universe and they are organized in a 1979 01:11:46,729 --> 01:11:44,940 hierarchy of controllers 1980 01:11:48,470 --> 01:11:46,739 and these controllers need to be turned 1981 01:11:50,030 --> 01:11:48,480 on and off at the level of the scene and 1982 01:11:51,590 --> 01:11:50,040 they have a lot of flexibility once you 1983 01:11:52,729 --> 01:11:51,600 have them they can move around in the 1984 01:11:54,590 --> 01:11:52,739 scene they're basically no 1985 01:11:57,050 --> 01:11:54,600 self-organizing self-stabilizing 1986 01:11:59,450 --> 01:11:57,060 entities in the same way as the mouse is 1987 01:12:01,310 --> 01:11:59,460 moving around in your organism a feature 1988 01:12:03,110 --> 01:12:01,320 can move around in the organism and 1989 01:12:05,450 --> 01:12:03,120 shift itself around to communicate with 1990 01:12:08,090 --> 01:12:05,460 other features until they negotiate a 1991 01:12:10,130 --> 01:12:08,100 valid interpretation of reality 1992 01:12:12,950 --> 01:12:10,140 that's that's incredibly interesting 1993 01:12:15,950 --> 01:12:12,960 because I you know as soon as you 1994 01:12:18,830 --> 01:12:15,960 started saying that uh I was starting to 1995 01:12:20,750 --> 01:12:18,840 think that the the virtualization that 1996 01:12:22,850 --> 01:12:20,760 enables right so the earlier part of 1997 01:12:24,250 --> 01:12:22,860 which we're saying the virtualization of 1998 01:12:27,410 --> 01:12:24,260 um 1999 01:12:28,370 --> 01:12:27,420 uh the the information that allows you 2000 01:12:30,229 --> 01:12:28,380 to 2001 01:12:33,410 --> 01:12:30,239 um deal with with unreliable hardware 2002 01:12:35,209 --> 01:12:33,420 and everything the the bioelectric uh 2003 01:12:36,770 --> 01:12:35,219 circuits that we deal with are a great 2004 01:12:39,229 --> 01:12:36,780 candidate for that because actually we 2005 01:12:41,209 --> 01:12:39,239 see exactly that we see a bioelectric 2006 01:12:43,310 --> 01:12:41,219 pattern that is very resistant to 2007 01:12:44,450 --> 01:12:43,320 changes in the details and make sure 2008 01:12:46,910 --> 01:12:44,460 that everybody does the right thing 2009 01:12:49,250 --> 01:12:46,920 under a wide range of you know different 2010 01:12:50,870 --> 01:12:49,260 defects and so on but but but even more 2011 01:12:52,729 --> 01:12:50,880 than that the other thing that what you 2012 01:12:54,410 --> 01:12:52,739 were just um emphasizing this the fact 2013 01:12:56,630 --> 01:12:54,420 that we learned the Delta right and that 2014 01:12:58,669 --> 01:12:56,640 and that we're looking for change very 2015 01:13:00,290 --> 01:12:58,679 interesting if you if you pivot the 2016 01:13:02,770 --> 01:13:00,300 whole thing from the temporal domain to 2017 01:13:05,930 --> 01:13:02,780 the spatial domain so so in development 2018 01:13:08,270 --> 01:13:05,940 what we we when we look at these 2019 01:13:10,070 --> 01:13:08,280 bioelectric patterns now now these 2020 01:13:11,870 --> 01:13:10,080 patterns are across space not across 2021 01:13:13,310 --> 01:13:11,880 time so so on like a neuroscience where 2022 01:13:15,410 --> 01:13:13,320 everything is kind of in the temporal 2023 01:13:17,870 --> 01:13:15,420 domain for neurons these things these 2024 01:13:19,490 --> 01:13:17,880 are voltage static voltage patterns 2025 01:13:22,729 --> 01:13:19,500 across tissue right across the whole 2026 01:13:24,709 --> 01:13:22,739 thing so for the longest time you know 2027 01:13:26,810 --> 01:13:24,719 we asked this question how are these 2028 01:13:28,790 --> 01:13:26,820 read out what how do cells actually read 2029 01:13:30,770 --> 01:13:28,800 these because because one possibility 2030 01:13:33,649 --> 01:13:30,780 early this was a very early hypothesis 2031 01:13:35,450 --> 01:13:33,659 you know 20 years ago was that maybe the 2032 01:13:37,189 --> 01:13:35,460 local voltage tells every cell what to 2033 01:13:39,490 --> 01:13:37,199 be so it's like a paint by numbers kind 2034 01:13:42,590 --> 01:13:39,500 of thing and every and and each voltage 2035 01:13:44,270 --> 01:13:42,600 you know each voltage value corresponds 2036 01:13:46,729 --> 01:13:44,280 to some kind of outcome that turned out 2037 01:13:48,530 --> 01:13:46,739 to be false what we did find is that 2038 01:13:51,050 --> 01:13:48,540 there and we have computational models 2039 01:13:54,410 --> 01:13:51,060 of how this works now 2040 01:13:56,570 --> 01:13:54,420 um what is read out is the Delta the 2041 01:13:58,010 --> 01:13:56,580 difference between regions it doesn't 2042 01:13:59,930 --> 01:13:58,020 care nobody cares about what the 2043 01:14:02,330 --> 01:13:59,940 absolute voltage is what what what is 2044 01:14:04,250 --> 01:14:02,340 read out in terms of outcomes for for 2045 01:14:06,290 --> 01:14:04,260 Downstream cell Behavior gene expression 2046 01:14:07,729 --> 01:14:06,300 all that what is actually right out is 2047 01:14:10,070 --> 01:14:07,739 the voltage difference between two 2048 01:14:11,689 --> 01:14:10,080 adjacent domains so that is exactly 2049 01:14:13,729 --> 01:14:11,699 actually what it's doing just in a 2050 01:14:16,970 --> 01:14:13,739 spatial domain it it only keys off of 2051 01:14:19,850 --> 01:14:16,980 the Delta and what is in what is learned 2052 01:14:21,709 --> 01:14:19,860 from that is um exactly just as as you 2053 01:14:23,810 --> 01:14:21,719 as you were saying it modifies uh the 2054 01:14:25,370 --> 01:14:23,820 controller for for what's Downstream of 2055 01:14:27,050 --> 01:14:25,380 that and there may be multiple ones that 2056 01:14:29,030 --> 01:14:27,060 are sort of moving around in Cohen 2057 01:14:30,169 --> 01:14:29,040 having I mean it's a very it's a very 2058 01:14:31,910 --> 01:14:30,179 compelling 2059 01:14:34,130 --> 01:14:31,920 um picture actually and way to look at 2060 01:14:36,410 --> 01:14:34,140 some of the some of the simulations that 2061 01:14:38,750 --> 01:14:36,420 that we've been doing about how the 2062 01:14:40,970 --> 01:14:38,760 bioelectric data are interpreted by the 2063 01:14:42,770 --> 01:14:40,980 rest of the cells you know it's very 2064 01:14:44,990 --> 01:14:42,780 interesting could we take a couple of 2065 01:14:46,790 --> 01:14:45,000 couple minute break yeah sure I'll get a 2066 01:14:48,890 --> 01:14:46,800 new coffee all right 2067 01:14:49,970 --> 01:14:48,900 speaking of coffee a brief note from our 2068 01:14:52,250 --> 01:14:49,980 sponsor 2069 01:14:54,169 --> 01:14:52,260 coffee helps me work it helps me fast 2070 01:14:56,270 --> 01:14:54,179 from carbs it's become one of the best 2071 01:14:57,649 --> 01:14:56,280 parts of my day consistently that's why 2072 01:14:59,750 --> 01:14:57,659 I'm delighted that we're collaborating 2073 01:15:01,910 --> 01:14:59,760 with Trade coffee they partner with top 2074 01:15:04,250 --> 01:15:01,920 independent Roasters to Freshly roast 2075 01:15:06,229 --> 01:15:04,260 and send the finest coffee in the 2076 01:15:08,330 --> 01:15:06,239 country directly to your home on your 2077 01:15:10,430 --> 01:15:08,340 preferred schedule this matters to me as 2078 01:15:12,649 --> 01:15:10,440 I work from home their team of experts 2079 01:15:15,229 --> 01:15:12,659 do all the work testing hundreds of 2080 01:15:18,590 --> 01:15:15,239 disparate coffees to land on a final 2081 01:15:20,930 --> 01:15:18,600 curated collection of 450 exceptional 2082 01:15:22,910 --> 01:15:20,940 coffees I chose these three and the team 2083 01:15:24,470 --> 01:15:22,920 at Trade coffee worked to create a 2084 01:15:26,510 --> 01:15:24,480 special lineup for theories of 2085 01:15:28,430 --> 01:15:26,520 everything for the tow audience based on 2086 01:15:30,350 --> 01:15:28,440 some questions they asked me such as how 2087 01:15:32,510 --> 01:15:30,360 much caffeine do I enjoy and what's the 2088 01:15:34,729 --> 01:15:32,520 bitterness ratio Etc you can get that 2089 01:15:36,770 --> 01:15:34,739 line up or if that's not let's say your 2090 01:15:39,169 --> 01:15:36,780 cup of coffee then you can take your own 2091 01:15:41,450 --> 01:15:39,179 quiz on their website to find a set that 2092 01:15:43,070 --> 01:15:41,460 matches your specific profile if you'd 2093 01:15:44,810 --> 01:15:43,080 like to support small businesses and 2094 01:15:47,390 --> 01:15:44,820 Brew the best cup of coffee you've ever 2095 01:15:49,550 --> 01:15:47,400 made at home then it's time to try Trade 2096 01:15:52,010 --> 01:15:49,560 coffee right now trade is offering our 2097 01:15:54,910 --> 01:15:52,020 listeners thirty dollars off your first 2098 01:15:58,450 --> 01:15:54,920 order plus free shipping at 2099 01:16:01,430 --> 01:15:58,460 drinktrade.com everything that's 2100 01:16:04,310 --> 01:16:01,440 drinktrade.com everything for thirty 2101 01:16:06,110 --> 01:16:04,320 dollars off so Professor Levin use the 2102 01:16:07,430 --> 01:16:06,120 word competence earlier and I'd like you 2103 01:16:08,510 --> 01:16:07,440 to Define that 2104 01:16:09,350 --> 01:16:08,520 yeah 2105 01:16:12,530 --> 01:16:09,360 um 2106 01:16:15,770 --> 01:16:12,540 I in order to Define it uh I I want to 2107 01:16:19,130 --> 01:16:15,780 put out two two concepts to this one one 2108 01:16:20,930 --> 01:16:19,140 idea is that to me and this goes back to 2109 01:16:24,649 --> 01:16:20,940 what we were talking about before is the 2110 01:16:28,610 --> 01:16:24,659 engineering stance on things I 2111 01:16:30,830 --> 01:16:28,620 think that useful cognitive claims such 2112 01:16:32,810 --> 01:16:30,840 as something you know when you say this 2113 01:16:34,790 --> 01:16:32,820 system has whatever or it can whatever 2114 01:16:36,709 --> 01:16:34,800 right as far as various types of 2115 01:16:38,870 --> 01:16:36,719 cognitive capacities I think those kind 2116 01:16:41,030 --> 01:16:38,880 of claims are really engineering uh 2117 01:16:43,189 --> 01:16:41,040 claims that is when you tell me that 2118 01:16:45,590 --> 01:16:43,199 something is competent at a particular 2119 01:16:47,450 --> 01:16:45,600 level maybe right so so you can think 2120 01:16:48,370 --> 01:16:47,460 about like like wiener and rosenberg's 2121 01:16:51,229 --> 01:16:48,380 scale of 2122 01:16:53,390 --> 01:16:51,239 cognition that goes from simple um you 2123 01:16:55,850 --> 01:16:53,400 know simple passive materials and then 2124 01:16:57,470 --> 01:16:55,860 reflexes and then all the way up to kind 2125 01:16:59,090 --> 01:16:57,480 of second order metacognition and all 2126 01:17:01,729 --> 01:16:59,100 that when you tell me that something is 2127 01:17:04,070 --> 01:17:01,739 on that ladder and where it is what 2128 01:17:06,709 --> 01:17:04,080 you're really telling me is if I want to 2129 01:17:08,689 --> 01:17:06,719 predict Its Behavior or I want to use it 2130 01:17:10,610 --> 01:17:08,699 in an engineering context or I want to 2131 01:17:13,070 --> 01:17:10,620 interact with it or relate to it in some 2132 01:17:14,390 --> 01:17:13,080 way this is what I can expect so right 2133 01:17:16,970 --> 01:17:14,400 so that's what you really telling me so 2134 01:17:19,010 --> 01:17:16,980 all of these terms what they really are 2135 01:17:22,430 --> 01:17:19,020 are engineering protocols so if you tell 2136 01:17:25,070 --> 01:17:22,440 me that something has the capacity to do 2137 01:17:26,750 --> 01:17:25,080 um a associate of learning or or 2138 01:17:28,550 --> 01:17:26,760 whatever what you're telling me is that 2139 01:17:30,229 --> 01:17:28,560 hey you can do something more with this 2140 01:17:33,350 --> 01:17:30,239 than you could with a mechanical clock 2141 01:17:35,209 --> 01:17:33,360 you can provide certain types of uh 2142 01:17:36,470 --> 01:17:35,219 stimuli or experiences and you can 2143 01:17:38,270 --> 01:17:36,480 expect that to do this or that 2144 01:17:40,970 --> 01:17:38,280 afterwards or if you tell me that 2145 01:17:43,370 --> 01:17:40,980 something is a um a homeous you know a 2146 01:17:46,010 --> 01:17:43,380 homeostat that means that hey I can 2147 01:17:47,990 --> 01:17:46,020 count on it to keep some variable in at 2148 01:17:50,209 --> 01:17:48,000 a particular range without having to be 2149 01:17:51,770 --> 01:17:50,219 there myself to control it all the way 2150 01:17:53,149 --> 01:17:51,780 it has a certain autonomy now how much 2151 01:17:55,550 --> 01:17:53,159 right and if you tell me that something 2152 01:17:57,530 --> 01:17:55,560 is really intelligent and it can do XYZ 2153 01:17:59,090 --> 01:17:57,540 then I know that okay you're telling me 2154 01:18:01,250 --> 01:17:59,100 that it has even more autonomous 2155 01:18:02,870 --> 01:18:01,260 behavior in certain contexts so so all 2156 01:18:04,850 --> 01:18:02,880 of these terms to me what they really 2157 01:18:06,350 --> 01:18:04,860 are they're not and that has an 2158 01:18:08,870 --> 01:18:06,360 important implication the implication is 2159 01:18:10,850 --> 01:18:08,880 that they're Observer dependent that 2160 01:18:13,370 --> 01:18:10,860 that that that you you've picked some 2161 01:18:15,290 --> 01:18:13,380 kind of problem space you've picked uh 2162 01:18:16,729 --> 01:18:15,300 some kind of perspective and from that 2163 01:18:18,590 --> 01:18:16,739 problem problem space in that 2164 01:18:21,229 --> 01:18:18,600 perspective you're telling me that with 2165 01:18:23,870 --> 01:18:21,239 with sort of given certain goal States 2166 01:18:25,610 --> 01:18:23,880 this system has that much competency to 2167 01:18:27,290 --> 01:18:25,620 pursue those gold States and different 2168 01:18:28,910 --> 01:18:27,300 observers can have different views on 2169 01:18:31,130 --> 01:18:28,920 this for any given system so for example 2170 01:18:33,229 --> 01:18:31,140 somebody might look at a brain like 2171 01:18:34,610 --> 01:18:33,239 let's say a human brain and say well I'm 2172 01:18:36,229 --> 01:18:34,620 pretty sure the only thing this is this 2173 01:18:38,090 --> 01:18:36,239 is a paperweight so it's really pretty 2174 01:18:39,890 --> 01:18:38,100 much just competent in going down 2175 01:18:41,570 --> 01:18:39,900 gravitational gradient so all I can do 2176 01:18:43,130 --> 01:18:41,580 is hold down paper that's it and 2177 01:18:44,270 --> 01:18:43,140 somebody else will look at and say ah 2178 01:18:45,110 --> 01:18:44,280 you missed the whole point you missed 2179 01:18:46,729 --> 01:18:45,120 the whole point this thing is 2180 01:18:49,550 --> 01:18:46,739 competencies in behavioral space and 2181 01:18:52,669 --> 01:18:49,560 linguistic space right so these are all 2182 01:18:54,350 --> 01:18:52,679 um empirically testable uh engineering 2183 01:18:56,390 --> 01:18:54,360 claims about what you can expect the 2184 01:18:59,810 --> 01:18:56,400 system to do so when I say competency 2185 01:19:01,430 --> 01:18:59,820 what I mean is we specify a space a 2186 01:19:02,450 --> 01:19:01,440 problem space and at the time when we 2187 01:19:05,090 --> 01:19:02,460 were talking about this the problem 2188 01:19:07,310 --> 01:19:05,100 space that I was talking about was the 2189 01:19:09,169 --> 01:19:07,320 the anatomical morphe space that was the 2190 01:19:10,610 --> 01:19:09,179 space we were talking about so so the 2191 01:19:12,590 --> 01:19:10,620 space of possible anatomical 2192 01:19:14,630 --> 01:19:12,600 configurations and specifically 2193 01:19:17,149 --> 01:19:14,640 navigating that morph of space so you 2194 01:19:19,790 --> 01:19:17,159 start off as an egg or you start off as 2195 01:19:22,070 --> 01:19:19,800 a damaged limb or whatever and you 2196 01:19:23,630 --> 01:19:22,080 navigate that morphe space into the 2197 01:19:25,790 --> 01:19:23,640 correct structure so so when I say 2198 01:19:28,850 --> 01:19:25,800 competency I mean you have the ability 2199 01:19:31,370 --> 01:19:28,860 to deploy certain kinds of tricks to 2200 01:19:34,910 --> 01:19:31,380 navigate that amorphous space with some 2201 01:19:36,530 --> 01:19:34,920 level of uh performance that I can count 2202 01:19:38,510 --> 01:19:36,540 on and so the competency might be really 2203 01:19:40,310 --> 01:19:38,520 low or it might be really high then I 2204 01:19:42,169 --> 01:19:40,320 would have to make specific claims about 2205 01:19:43,790 --> 01:19:42,179 what I mean here's an example of a 2206 01:19:44,930 --> 01:19:43,800 compound and there are many you know if 2207 01:19:46,729 --> 01:19:44,940 you just think about the Behavioral 2208 01:19:48,830 --> 01:19:46,739 Science of navigation there are many 2209 01:19:50,630 --> 01:19:48,840 competencies you can think about does it 2210 01:19:51,950 --> 01:19:50,640 you know does it does it know ahead of 2211 01:19:54,350 --> 01:19:51,960 time where it's going does it have a 2212 01:19:56,810 --> 01:19:54,360 memory of where it's been or is it a 2213 01:19:59,870 --> 01:19:56,820 very simple you know sort of reflex arc 2214 01:20:01,970 --> 01:19:59,880 is all it has or um here's one one 2215 01:20:04,070 --> 01:20:01,980 example of a pretty cool competency that 2216 01:20:04,729 --> 01:20:04,080 um that that a lot of biological systems 2217 01:20:08,570 --> 01:20:04,739 have 2218 01:20:11,050 --> 01:20:08,580 if we take some cells that are in the 2219 01:20:14,570 --> 01:20:11,060 tail of a tadpole and we 2220 01:20:16,910 --> 01:20:14,580 give them a particular we we modify 2221 01:20:19,550 --> 01:20:16,920 their ion channels uh with such that 2222 01:20:22,370 --> 01:20:19,560 they now acquire 2223 01:20:24,290 --> 01:20:22,380 um a a the goal of navigating to an eye 2224 01:20:25,490 --> 01:20:24,300 fate in more in in this morphe space 2225 01:20:27,590 --> 01:20:25,500 meaning that they're going to make an 2226 01:20:28,850 --> 01:20:27,600 eye these things in fact will create an 2227 01:20:30,950 --> 01:20:28,860 eye and they'll make an eye in the tail 2228 01:20:32,750 --> 01:20:30,960 on the gut wherever you want but one of 2229 01:20:34,729 --> 01:20:32,760 the cool and so that's already pretty 2230 01:20:38,630 --> 01:20:34,739 pretty cool but but one of the amazing 2231 01:20:40,550 --> 01:20:38,640 aspects is if I only modify a few cells 2232 01:20:42,290 --> 01:20:40,560 not enough to make an actual eye just 2233 01:20:43,970 --> 01:20:42,300 just a handful of cells and we've done 2234 01:20:46,850 --> 01:20:43,980 this and you can see this work 2235 01:20:48,590 --> 01:20:46,860 one of the competencies they have is to 2236 01:20:51,229 --> 01:20:48,600 recruit local neighbors that were 2237 01:20:53,030 --> 01:20:51,239 themselves not in any way manipulated to 2238 01:20:54,410 --> 01:20:53,040 help them achieve that goal it's a 2239 01:20:55,790 --> 01:20:54,420 little bit like in an ant colony right 2240 01:20:57,290 --> 01:20:55,800 there's a there's this idea of 2241 01:20:58,490 --> 01:20:57,300 Recruitment and ants and termites is an 2242 01:21:00,530 --> 01:20:58,500 idea of recruitment where where 2243 01:21:01,610 --> 01:21:00,540 individuals can can recruit others and 2244 01:21:03,350 --> 01:21:01,620 you know talk about a flexible 2245 01:21:05,750 --> 01:21:03,360 collective intelligence this is it this 2246 01:21:08,090 --> 01:21:05,760 is they they you you've re-specified the 2247 01:21:09,649 --> 01:21:08,100 goal for that set of cells but one of 2248 01:21:11,930 --> 01:21:09,659 the things that they do without us 2249 01:21:13,910 --> 01:21:11,940 telling them how to do it or having to 2250 01:21:16,070 --> 01:21:13,920 micromanage it they already have the 2251 01:21:18,950 --> 01:21:16,080 competency to recruit as many cells as 2252 01:21:20,630 --> 01:21:18,960 they need to get the job done so that's 2253 01:21:22,490 --> 01:21:20,640 a very nice for an engineer that's a 2254 01:21:24,830 --> 01:21:22,500 very nice competency because it means 2255 01:21:26,750 --> 01:21:24,840 that I don't need to worry about taking 2256 01:21:29,270 --> 01:21:26,760 care of getting exactly the right number 2257 01:21:31,250 --> 01:21:29,280 of cells if I'm if I'm a little bit over 2258 01:21:33,110 --> 01:21:31,260 that's fine if I'm way under also fine 2259 01:21:35,510 --> 01:21:33,120 the system has that competency of 2260 01:21:37,189 --> 01:21:35,520 recruiting other cells to get the job 2261 01:21:39,410 --> 01:21:37,199 done so so that's what I so that's what 2262 01:21:40,970 --> 01:21:39,420 I meant so to me to make an um any kind 2263 01:21:43,610 --> 01:21:40,980 of a cognitive claim you have to specify 2264 01:21:45,350 --> 01:21:43,620 the problem space you have to specify 2265 01:21:47,330 --> 01:21:45,360 the goal goal towards which it's 2266 01:21:49,310 --> 01:21:47,340 expressing competencies and that may 2267 01:21:51,229 --> 01:21:49,320 right and and then and then you can make 2268 01:21:53,390 --> 01:21:51,239 a claim about well how competent is it 2269 01:21:54,709 --> 01:21:53,400 to get to that goal and somebody I wish 2270 01:21:56,510 --> 01:21:54,719 I could remember who it was but somebody 2271 01:21:58,250 --> 01:21:56,520 made this really nice analogy about kind 2272 01:22:00,950 --> 01:21:58,260 of the ends of that spectrum they said 2273 01:22:03,229 --> 01:22:00,960 two magnets try to get together and 2274 01:22:05,030 --> 01:22:03,239 Romeo and Juliet try to get together but 2275 01:22:06,410 --> 01:22:05,040 the degree of flexible problem solving 2276 01:22:09,229 --> 01:22:06,420 that you can expect out of those two 2277 01:22:11,090 --> 01:22:09,239 systems is incredibly different and 2278 01:22:12,950 --> 01:22:11,100 within that range there are all kinds of 2279 01:22:14,570 --> 01:22:12,960 in-between systems that may be better or 2280 01:22:16,430 --> 01:22:14,580 worse and may deploy different kinds of 2281 01:22:18,470 --> 01:22:16,440 strategies you know can they avoid local 2282 01:22:20,390 --> 01:22:18,480 Optima can they have a memory of the 2283 01:22:22,010 --> 01:22:20,400 where they've been can they look further 2284 01:22:23,570 --> 01:22:22,020 than their local environment a million 2285 01:22:25,130 --> 01:22:23,580 different things so that's that's what I 2286 01:22:28,189 --> 01:22:25,140 meant by competency it's it's it's it's 2287 01:22:30,950 --> 01:22:28,199 a claim about what and what an engineer 2288 01:22:32,689 --> 01:22:30,960 can expect the system to do given a 2289 01:22:34,850 --> 01:22:32,699 particular problem space in a particular 2290 01:22:35,930 --> 01:22:34,860 goal that you think it's uh trying to 2291 01:22:37,669 --> 01:22:35,940 reach 2292 01:22:42,050 --> 01:22:37,679 so the way in which you use the word 2293 01:22:43,790 --> 01:22:42,060 competency could be treated as the 2294 01:22:46,130 --> 01:22:43,800 capacity of a system for adaptive 2295 01:22:51,110 --> 01:22:48,070 yeah yeah yeah 2296 01:22:53,209 --> 01:22:51,120 one uh issue that I have with the notion 2297 01:22:55,610 --> 01:22:53,219 of goals and goal directedness is that 2298 01:22:58,250 --> 01:22:55,620 sometimes you only have a tendency in a 2299 01:23:00,830 --> 01:22:58,260 system to go in a certain direction and 2300 01:23:03,350 --> 01:23:00,840 so it's it's directed but the goal is 2301 01:23:05,030 --> 01:23:03,360 something that can be emergent sometimes 2302 01:23:06,470 --> 01:23:05,040 it's not sometimes there is an explicit 2303 01:23:08,270 --> 01:23:06,480 representation in the system of a 2304 01:23:10,310 --> 01:23:08,280 discrete event that is associated or a 2305 01:23:11,990 --> 01:23:10,320 class of events this fulfilling a 2306 01:23:13,430 --> 01:23:12,000 certain condition that the system has 2307 01:23:14,990 --> 01:23:13,440 committed itself to and if you don't 2308 01:23:17,390 --> 01:23:15,000 have that you don't have a proper goal 2309 01:23:20,630 --> 01:23:17,400 but in real systems it's difficult to 2310 01:23:22,910 --> 01:23:20,640 say I mean when do we pursue goals right 2311 01:23:24,830 --> 01:23:22,920 sometimes we just are vaguely hungry are 2312 01:23:26,270 --> 01:23:24,840 moving towards the kitchen because we 2313 01:23:28,550 --> 01:23:26,280 hope that something will 2314 01:23:31,370 --> 01:23:28,560 opportunistically emerge that will deal 2315 01:23:33,229 --> 01:23:31,380 with this vague tendency in our Behavior 2316 01:23:35,390 --> 01:23:33,239 we could also say we have the goal of 2317 01:23:37,490 --> 01:23:35,400 finding food but uh that is a 2318 01:23:40,729 --> 01:23:37,500 rationalization that is maybe stretching 2319 01:23:42,530 --> 01:23:40,739 sick sometimes yeah so uh sometimes a 2320 01:23:44,870 --> 01:23:42,540 better distinction for me is 2321 01:23:47,750 --> 01:23:44,880 going from a simple controller to an 2322 01:23:49,610 --> 01:23:47,760 agent and I try to because we are very 2323 01:23:51,050 --> 01:23:49,620 good at discovering agency in the world 2324 01:23:53,149 --> 01:23:51,060 what does it actually mean when we 2325 01:23:56,330 --> 01:23:53,159 discover agency and when we discover our 2326 01:23:56,930 --> 01:23:56,340 own agency and start to amplify it 2327 01:23:59,209 --> 01:23:56,940 um 2328 01:24:00,950 --> 01:23:59,219 by making models of who we are and how 2329 01:24:02,990 --> 01:24:00,960 we deal with the world and with others 2330 01:24:04,729 --> 01:24:03,000 and so on the minimal definition of 2331 01:24:06,290 --> 01:24:04,739 agent that I found it's a controller for 2332 01:24:08,630 --> 01:24:06,300 future States 2333 01:24:11,390 --> 01:24:08,640 the thermostat doesn't have a goal by 2334 01:24:14,149 --> 01:24:11,400 itself right it just has a Target value 2335 01:24:15,890 --> 01:24:14,159 and a sensor that tells the deviation 2336 01:24:18,169 --> 01:24:15,900 from the target value and when that 2337 01:24:21,530 --> 01:24:18,179 exceeds a certain threshold the heating 2338 01:24:22,850 --> 01:24:21,540 is turned on and if it goes below a 2339 01:24:24,950 --> 01:24:22,860 certain threshold the heating is turned 2340 01:24:26,510 --> 01:24:24,960 off again and this is it so the 2341 01:24:29,570 --> 01:24:26,520 thermostat is not an age and it only 2342 01:24:30,830 --> 01:24:29,580 reacts to the present frame it's only a 2343 01:24:33,350 --> 01:24:30,840 reactive system 2344 01:24:36,169 --> 01:24:33,360 whereas an agent is proactive which 2345 01:24:38,930 --> 01:24:36,179 means that it's trying to um not just 2346 01:24:41,810 --> 01:24:38,940 minimize the current deviation from the 2347 01:24:43,370 --> 01:24:41,820 target value but the integral over at 2348 01:24:45,770 --> 01:24:43,380 the time span previously the future 2349 01:24:49,189 --> 01:24:45,780 deviation so it builds an expectation 2350 01:24:51,530 --> 01:24:49,199 about how uh an action is going to 2351 01:24:54,110 --> 01:24:51,540 change this trajectory of the universe 2352 01:24:57,110 --> 01:24:54,120 and over that trajectory it tries to 2353 01:24:59,750 --> 01:24:57,120 figure out some measure of how big the 2354 01:25:02,030 --> 01:24:59,760 compound Target deviation is going to be 2355 01:25:03,890 --> 01:25:02,040 and so as a result you get a branching 2356 01:25:05,390 --> 01:25:03,900 universe and the branches in this 2357 01:25:08,090 --> 01:25:05,400 universe some of these branches depend 2358 01:25:09,950 --> 01:25:08,100 on actions that are available to you and 2359 01:25:13,669 --> 01:25:09,960 that translate into decisions that you 2360 01:25:15,050 --> 01:25:13,679 can make that uh move you into more or 2361 01:25:16,729 --> 01:25:15,060 less preferable wealth States and 2362 01:25:19,610 --> 01:25:16,739 suddenly you have a system with emergent 2363 01:25:22,070 --> 01:25:19,620 beliefs desires and intentions but to 2364 01:25:25,010 --> 01:25:22,080 make that happen to move from a 2365 01:25:27,290 --> 01:25:25,020 controller to agency and agent has been 2366 01:25:30,470 --> 01:25:27,300 a controller with an integrated setpoint 2367 01:25:33,110 --> 01:25:30,480 generator and the ability to control 2368 01:25:36,590 --> 01:25:33,120 future states that requires that you can 2369 01:25:38,570 --> 01:25:36,600 make models that are counterfactual so 2370 01:25:41,030 --> 01:25:38,580 because the future universe doesn't 2371 01:25:43,130 --> 01:25:41,040 exist right now you need to create a 2372 01:25:45,350 --> 01:25:43,140 counterfactual universe The Future model 2373 01:25:46,910 --> 01:25:45,360 of the future Universe maybe even a 2374 01:25:48,350 --> 01:25:46,920 model of the past universe that allows 2375 01:25:50,750 --> 01:25:48,360 you to reason about possible for future 2376 01:25:53,030 --> 01:25:50,760 universes and so on and to make these 2377 01:25:54,890 --> 01:25:53,040 counter factual causal models of the 2378 01:25:55,970 --> 01:25:54,900 universe you need to have a turing 2379 01:25:58,129 --> 01:25:55,980 machine 2380 01:26:00,890 --> 01:25:58,139 so without a computer without something 2381 01:26:02,810 --> 01:26:00,900 that is too incomplete that insulates 2382 01:26:05,270 --> 01:26:02,820 you from the causal structure of your 2383 01:26:07,250 --> 01:26:05,280 substrate that allows you to build 2384 01:26:09,590 --> 01:26:07,260 representations regardless of what the 2385 01:26:11,510 --> 01:26:09,600 universe says right now around you right 2386 01:26:14,510 --> 01:26:11,520 you need to have that machine and the 2387 01:26:17,149 --> 01:26:14,520 simplest uh system in nature that has 2388 01:26:19,669 --> 01:26:17,159 turing machine integrated is the cell 2389 01:26:22,490 --> 01:26:19,679 so uh it's very difficult to find a 2390 01:26:25,250 --> 01:26:22,500 system in nature that is an agent that 2391 01:26:27,229 --> 01:26:25,260 is not made from cells as a result 2392 01:26:29,510 --> 01:26:27,239 maybe there are systems in nature that 2393 01:26:32,990 --> 01:26:29,520 are able to uh compute things and make 2394 01:26:35,810 --> 01:26:33,000 models but uh I I'm not aware of any so 2395 01:26:37,810 --> 01:26:35,820 the simplest one that I know that can do 2396 01:26:41,750 --> 01:26:37,820 this reliably is the cells or 2397 01:26:44,390 --> 01:26:41,760 arrangement of sets and that can possess 2398 01:26:46,970 --> 01:26:44,400 agency which is interesting thing that 2399 01:26:49,669 --> 01:26:46,980 explains this coincidence that living 2400 01:26:51,470 --> 01:26:49,679 things are agents and vice versa that 2401 01:26:53,750 --> 01:26:51,480 the agent that we discover are mostly 2402 01:26:56,570 --> 01:26:53,760 living things or there are robots that 2403 01:26:59,689 --> 01:26:56,580 have computers built into them or uh 2404 01:27:01,910 --> 01:26:59,699 virtual robots that have that rely on 2405 01:27:04,070 --> 01:27:01,920 computation so the ability to make 2406 01:27:06,770 --> 01:27:04,080 models of the future is the prerequisite 2407 01:27:09,770 --> 01:27:06,780 for agency and to make arbitrary models 2408 01:27:13,970 --> 01:27:09,780 which means structures that embody uh 2409 01:27:16,550 --> 01:27:13,980 causal uh simulations of some sort that 2410 01:27:19,610 --> 01:27:16,560 requires computation 2411 01:27:21,470 --> 01:27:19,620 yeah yeah um you know I'm on board with 2412 01:27:24,530 --> 01:27:21,480 that with that ladder of that that 2413 01:27:26,629 --> 01:27:24,540 taxonomy uh of of uh 2414 01:27:28,669 --> 01:27:26,639 of of goals and so on one one 2415 01:27:30,530 --> 01:27:28,679 interesting thing about uh about goals 2416 01:27:32,209 --> 01:27:30,540 and as you say some are emergent and and 2417 01:27:34,010 --> 01:27:32,219 some are not there's a there's an 2418 01:27:36,709 --> 01:27:34,020 interesting uh planarian 2419 01:27:37,850 --> 01:27:36,719 um uh version of this which is which is 2420 01:27:41,149 --> 01:27:37,860 this we 2421 01:27:42,770 --> 01:27:41,159 we made this hypothesis about so so with 2422 01:27:44,810 --> 01:27:42,780 implant area you chop it up into pieces 2423 01:27:46,610 --> 01:27:44,820 and every piece regenerates exactly the 2424 01:27:48,950 --> 01:27:46,620 right rest of the work right so if it's 2425 01:27:51,950 --> 01:27:48,960 if if you chop it into pieces each piece 2426 01:27:53,570 --> 01:27:51,960 will have one head one tail so and then 2427 01:27:55,310 --> 01:27:53,580 and then of course what happens is it 2428 01:27:57,649 --> 01:27:55,320 stops when it when it may when it 2429 01:28:00,830 --> 01:27:57,659 reaches a correct planarian then then it 2430 01:28:01,970 --> 01:28:00,840 stops and so so we started to think that 2431 01:28:03,709 --> 01:28:01,980 there are two there are a couple of 2432 01:28:06,110 --> 01:28:03,719 possibilities one possibility is that 2433 01:28:08,030 --> 01:28:06,120 this is a purely emergent process and 2434 01:28:10,189 --> 01:28:08,040 that the goal of rebuilding ahead is is 2435 01:28:12,410 --> 01:28:10,199 an emergent thing that comes about as a 2436 01:28:14,870 --> 01:28:12,420 consequence of other things or could 2437 01:28:16,550 --> 01:28:14,880 there be a an actual explicit 2438 01:28:18,709 --> 01:28:16,560 representation of what a correct 2439 01:28:20,810 --> 01:28:18,719 planarian is that serves as a set point 2440 01:28:22,850 --> 01:28:20,820 as an encoded as an explicitly encoded 2441 01:28:24,970 --> 01:28:22,860 set point for these cells to follow and 2442 01:28:27,169 --> 01:28:24,980 and because it's a cellular a collective 2443 01:28:29,330 --> 01:28:27,179 we're communicating electrically we 2444 01:28:32,149 --> 01:28:29,340 thought well maybe maybe what it's doing 2445 01:28:34,790 --> 01:28:32,159 is basically storing a memory of what 2446 01:28:36,709 --> 01:28:34,800 did you like you would in in a neural 2447 01:28:38,390 --> 01:28:36,719 circuit you're storing a memory of what 2448 01:28:39,770 --> 01:28:38,400 it should be so we started looking for 2449 01:28:42,470 --> 01:28:39,780 this and this is what we found and this 2450 01:28:45,290 --> 01:28:42,480 is this is kind of I think one type of 2451 01:28:48,229 --> 01:28:45,300 one one important type of goal in a in a 2452 01:28:50,990 --> 01:28:48,239 goal seeking system is is a is a goal 2453 01:28:52,490 --> 01:28:51,000 that you can rewrite without changing 2454 01:28:54,110 --> 01:28:52,500 the hardware and the system will now 2455 01:28:56,330 --> 01:28:54,120 pursue that goal instead of something 2456 01:28:57,649 --> 01:28:56,340 else in a purely emergent system that 2457 01:28:59,750 --> 01:28:57,659 doesn't work right if you have a 2458 01:29:01,010 --> 01:28:59,760 cellular automaton or a fractal or 2459 01:29:02,810 --> 01:29:01,020 something that that does some kind of 2460 01:29:04,129 --> 01:29:02,820 complex thing if you want to change what 2461 01:29:05,689 --> 01:29:04,139 that complex thing is you have to figure 2462 01:29:07,550 --> 01:29:05,699 out what the local rule how to change 2463 01:29:09,770 --> 01:29:07,560 the local rules that's very hard in most 2464 01:29:12,350 --> 01:29:09,780 cases but what we found in planaria is 2465 01:29:15,290 --> 01:29:12,360 that we can literally using a voltage 2466 01:29:18,530 --> 01:29:15,300 reporter die we can look at the worm and 2467 01:29:19,970 --> 01:29:18,540 we can see now the pattern the the and 2468 01:29:21,590 --> 01:29:19,980 it's a distributed pattern but we can 2469 01:29:23,689 --> 01:29:21,600 see the pattern that tells this animal 2470 01:29:25,850 --> 01:29:23,699 how many heads it's supposed to have and 2471 01:29:29,810 --> 01:29:25,860 what you can do is you can go in and 2472 01:29:31,550 --> 01:29:29,820 using a a brief transient uh 2473 01:29:33,950 --> 01:29:31,560 manipulation of the ion Channels with 2474 01:29:35,450 --> 01:29:33,960 drugs with ION channel drugs that and we 2475 01:29:37,189 --> 01:29:35,460 have a computational model that tells 2476 01:29:39,770 --> 01:29:37,199 you what those drugs should be that 2477 01:29:41,629 --> 01:29:39,780 bring briefly changes the electrical 2478 01:29:43,550 --> 01:29:41,639 state of the circuit but the circuit is 2479 01:29:46,430 --> 01:29:43,560 amazing it's it it once you've changed 2480 01:29:48,169 --> 01:29:46,440 that state it holds so so by default it 2481 01:29:50,090 --> 01:29:48,179 in a standard planarian it always says 2482 01:29:51,410 --> 01:29:50,100 one head but but it's kind of like a 2483 01:29:53,629 --> 01:29:51,420 flip-flop in that when you you 2484 01:29:55,430 --> 01:29:53,639 temporarily shift it it holds and you 2485 01:29:57,050 --> 01:29:55,440 can push it to a to a state that says 2486 01:29:58,729 --> 01:29:57,060 two heads so now something very 2487 01:30:00,590 --> 01:29:58,739 interesting happens 2488 01:30:02,270 --> 01:30:00,600 um two interesting things one is that if 2489 01:30:04,669 --> 01:30:02,280 you if you take those worms and you cut 2490 01:30:06,290 --> 01:30:04,679 those into pieces you get two-headed 2491 01:30:07,850 --> 01:30:06,300 worms even though the genetics are the 2492 01:30:09,229 --> 01:30:07,860 hardware is all wild type there's 2493 01:30:10,669 --> 01:30:09,239 nothing wrong with Hardware all the 2494 01:30:12,649 --> 01:30:10,679 proteins are the same all the genetics 2495 01:30:14,750 --> 01:30:12,659 is the same but the electric circuit now 2496 01:30:17,570 --> 01:30:14,760 says make two heads instead of one and 2497 01:30:19,669 --> 01:30:17,580 so this is in in an interesting way it 2498 01:30:21,169 --> 01:30:19,679 is an explicit goal because you can 2499 01:30:22,610 --> 01:30:21,179 rewrite it because much like with your 2500 01:30:24,350 --> 01:30:22,620 thermostat there's an interface for 2501 01:30:25,550 --> 01:30:24,360 changing what the goal state is and then 2502 01:30:26,870 --> 01:30:25,560 you don't even need to know how the rest 2503 01:30:28,729 --> 01:30:26,880 of the thermostat works as long as you 2504 01:30:30,530 --> 01:30:28,739 know how to use your how to modify that 2505 01:30:32,750 --> 01:30:30,540 interface the system takes care of the 2506 01:30:34,070 --> 01:30:32,760 rest the other interesting thing is and 2507 01:30:37,250 --> 01:30:34,080 and I love what you said about the 2508 01:30:39,770 --> 01:30:37,260 counter factuals what you can do is you 2509 01:30:41,330 --> 01:30:39,780 can change that electrical pattern in an 2510 01:30:44,209 --> 01:30:41,340 intact worm 2511 01:30:45,410 --> 01:30:44,219 and not cut it for a long time and if 2512 01:30:47,030 --> 01:30:45,420 you do that when you look at that 2513 01:30:49,669 --> 01:30:47,040 pattern that is a counter factual 2514 01:30:52,610 --> 01:30:49,679 pattern because that two-headed pattern 2515 01:30:54,050 --> 01:30:52,620 is not a readout of the current state it 2516 01:30:56,510 --> 01:30:54,060 says two heads but the animal only has 2517 01:30:59,030 --> 01:30:56,520 one head it's a normal planarian so the 2518 01:31:01,430 --> 01:30:59,040 that pattern memory is not a readout of 2519 01:31:03,590 --> 01:31:01,440 what the animal is doing right now it is 2520 01:31:05,750 --> 01:31:03,600 a representation of what the animal will 2521 01:31:07,669 --> 01:31:05,760 do in the future if it happens to get 2522 01:31:09,530 --> 01:31:07,679 injured and you may never cut it or you 2523 01:31:11,570 --> 01:31:09,540 may cut it but if you do then the 2524 01:31:13,550 --> 01:31:11,580 pattern becomes uh then the cells 2525 01:31:15,229 --> 01:31:13,560 consult a pattern and build a two-headed 2526 01:31:17,390 --> 01:31:15,239 worm and then it becomes a you know the 2527 01:31:19,250 --> 01:31:17,400 current state but until then it's this 2528 01:31:21,229 --> 01:31:19,260 weird like primitive 2529 01:31:23,629 --> 01:31:21,239 um uh it's a primitive counterfactual 2530 01:31:26,930 --> 01:31:23,639 system because it's able to a body of a 2531 01:31:27,830 --> 01:31:26,940 planarian is able to store at least two 2532 01:31:30,169 --> 01:31:27,840 different 2533 01:31:32,330 --> 01:31:30,179 representations of what probably many 2534 01:31:33,770 --> 01:31:32,340 more but we found two so far what a 2535 01:31:35,330 --> 01:31:33,780 correct planarian should look like it 2536 01:31:36,890 --> 01:31:35,340 can have a memory of a one-headed 2537 01:31:39,770 --> 01:31:36,900 planarian or a memory of a two-headed 2538 01:31:41,750 --> 01:31:39,780 planarian and and and both of those can 2539 01:31:43,970 --> 01:31:41,760 live in exactly the same Hardware in 2540 01:31:46,250 --> 01:31:43,980 exactly the same the same body the other 2541 01:31:48,050 --> 01:31:46,260 kind of cool thing about this and um 2542 01:31:50,450 --> 01:31:48,060 I'll just mention this even though this 2543 01:31:52,669 --> 01:31:50,460 is this is you know disclaimer this is 2544 01:31:54,169 --> 01:31:52,679 not published yet so this is uh you know 2545 01:31:56,629 --> 01:31:54,179 take all this with a grain of salt the 2546 01:31:58,910 --> 01:31:56,639 the but but the the latest thing you can 2547 01:32:00,770 --> 01:31:58,920 do is you can actually treat it with 2548 01:32:03,350 --> 01:32:00,780 some of the same compounds that are used 2549 01:32:06,169 --> 01:32:03,360 in uh Neuroscience in in humans and in 2550 01:32:08,149 --> 01:32:06,179 rats as memory blockers so so things 2551 01:32:10,430 --> 01:32:08,159 that block recall or or memory 2552 01:32:11,990 --> 01:32:10,440 consolidation and when you do that you 2553 01:32:13,430 --> 01:32:12,000 can make the animal forget how many 2554 01:32:14,930 --> 01:32:13,440 heads it's supposed to have and then 2555 01:32:17,090 --> 01:32:14,940 they basically turn into a featureless 2556 01:32:18,709 --> 01:32:17,100 circle when when you can just wipe you 2557 01:32:20,270 --> 01:32:18,719 can just wipe the the pattern memory 2558 01:32:22,370 --> 01:32:20,280 completely with it using exactly the 2559 01:32:24,709 --> 01:32:22,380 same techniques you would use in a in a 2560 01:32:26,209 --> 01:32:24,719 rat or a human they just forget what to 2561 01:32:27,770 --> 01:32:26,219 do when they turn into they fail to 2562 01:32:31,550 --> 01:32:27,780 break Symmetry and they just become a 2563 01:32:33,470 --> 01:32:31,560 Circle so yeah I I think I think what 2564 01:32:35,870 --> 01:32:33,480 you were saying is is right on with with 2565 01:32:37,729 --> 01:32:35,880 this this ability to uh store 2566 01:32:39,890 --> 01:32:37,739 counterfactual states that are not true 2567 01:32:41,750 --> 01:32:39,900 now but may represent 2568 01:32:44,090 --> 01:32:41,760 aspects of the of the future I think 2569 01:32:46,510 --> 01:32:44,100 that's that's a very important capacity 2570 01:32:49,430 --> 01:32:46,520 another important notion is a constraint 2571 01:32:52,070 --> 01:32:49,440 uh constraint satisfaction a constraint 2572 01:32:54,110 --> 01:32:52,080 is a rule that tells you uh whether two 2573 01:32:55,490 --> 01:32:54,120 things are compatible or not and the 2574 01:32:57,410 --> 01:32:55,500 constraint is satisfied if they're 2575 01:32:59,030 --> 01:32:57,420 compatible so you basically have a 2576 01:33:01,330 --> 01:32:59,040 number of conditions that you establish 2577 01:33:04,310 --> 01:33:01,340 by measuring that somehow for instance 2578 01:33:07,250 --> 01:33:04,320 uh whether you have a head or multiple 2579 01:33:09,169 --> 01:33:07,260 heads and you try to find a solution 2580 01:33:11,390 --> 01:33:09,179 where you can end up with exactly one 2581 01:33:13,970 --> 01:33:11,400 head and if you end up with exactly one 2582 01:33:15,530 --> 01:33:13,980 head based on the starting State then 2583 01:33:18,770 --> 01:33:15,540 you have managed to find a way to 2584 01:33:21,530 --> 01:33:18,780 satisfy your constraints and so in a 2585 01:33:24,890 --> 01:33:21,540 sense uh what you call a competency is 2586 01:33:27,709 --> 01:33:24,900 the ability of a system to take a region 2587 01:33:30,290 --> 01:33:27,719 of this of states of the space of the 2588 01:33:32,090 --> 01:33:30,300 universe some basically some local 2589 01:33:36,470 --> 01:33:32,100 region of possible state that the Euros 2590 01:33:39,410 --> 01:33:36,480 can be in and move that region to a 2591 01:33:40,669 --> 01:33:39,420 smaller region that is acceptable so the 2592 01:33:42,110 --> 01:33:40,679 basically there is a region on the 2593 01:33:43,070 --> 01:33:42,120 universe State space where you have only 2594 01:33:44,689 --> 01:33:43,080 one head 2595 01:33:46,189 --> 01:33:44,699 and there's a larger region where you 2596 01:33:48,530 --> 01:33:46,199 don't have any head at all but the 2597 01:33:50,930 --> 01:33:48,540 starting state of your organism and then 2598 01:33:52,910 --> 01:33:50,940 you try to get from A to B so you get 2599 01:33:55,010 --> 01:33:52,920 from this larger region to the one in 2600 01:33:56,390 --> 01:33:55,020 which you want to be of course if you 2601 01:33:58,610 --> 01:33:56,400 have one head you want to stay in the 2602 01:34:00,709 --> 01:33:58,620 region in which you have one head which 2603 01:34:02,750 --> 01:34:00,719 of course is usually much easier but the 2604 01:34:06,290 --> 01:34:02,760 ability basically to condense the space 2605 01:34:09,290 --> 01:34:06,300 to get to Bridge Over many regions into 2606 01:34:11,090 --> 01:34:09,300 the target region is what comes down to 2607 01:34:13,490 --> 01:34:11,100 this this is what this competency is the 2608 01:34:15,470 --> 01:34:13,500 system basically has an emergent wanting 2609 01:34:17,330 --> 01:34:15,480 to go in this region and it's trying to 2610 01:34:19,310 --> 01:34:17,340 move there and so there are constraints 2611 01:34:21,530 --> 01:34:19,320 on the level of the substrate 2612 01:34:23,330 --> 01:34:21,540 uh that are battling with the functional 2613 01:34:25,430 --> 01:34:23,340 constraints that the organism wants to 2614 01:34:28,189 --> 01:34:25,440 realize to fulfill its function and 2615 01:34:29,510 --> 01:34:28,199 sometimes uh you cannot satisfy this and 2616 01:34:30,830 --> 01:34:29,520 you end up with two heads because you 2617 01:34:33,890 --> 01:34:30,840 don't know which one you'll get rid of 2618 01:34:37,010 --> 01:34:33,900 or how to digest one of the heads and so 2619 01:34:40,310 --> 01:34:37,020 on and you end up with some Siamese twin 2620 01:34:42,169 --> 01:34:40,320 and uh so this this is an interesting 2621 01:34:44,629 --> 01:34:42,179 constraint that you have to solve for 2622 01:34:46,430 --> 01:34:44,639 when you are dealing with reality and 2623 01:34:49,550 --> 01:34:46,440 how you battle with the substrate until 2624 01:34:50,950 --> 01:34:49,560 you get to the functional solution that 2625 01:34:53,510 --> 01:34:50,960 you evolve for 2626 01:34:56,570 --> 01:34:53,520 yeah it's that's that's interesting I 2627 01:35:00,229 --> 01:34:56,580 mean we we've also found that there are 2628 01:35:02,390 --> 01:35:00,239 so so we look at exactly this uh the the 2629 01:35:03,830 --> 01:35:02,400 navigation this kind of navigation and 2630 01:35:05,629 --> 01:35:03,840 Morpher space how you get from here to 2631 01:35:07,790 --> 01:35:05,639 there and what paths are possible to get 2632 01:35:10,129 --> 01:35:07,800 from here to there and so on one of the 2633 01:35:12,350 --> 01:35:10,139 things that we found is that there are 2634 01:35:15,709 --> 01:35:12,360 regions of that space that belong to 2635 01:35:17,990 --> 01:35:15,719 other species and you can you can push a 2636 01:35:20,750 --> 01:35:18,000 a planarian with a standard wild type 2637 01:35:22,070 --> 01:35:20,760 genome into the goal state of a 2638 01:35:23,810 --> 01:35:22,080 completely different species so we can 2639 01:35:25,310 --> 01:35:23,820 get them to grow ahead so there's a 2640 01:35:27,050 --> 01:35:25,320 species that normally has a triangular 2641 01:35:28,970 --> 01:35:27,060 head you can make it grow a round head 2642 01:35:32,030 --> 01:35:28,980 like a like an like a different species 2643 01:35:35,450 --> 01:35:32,040 or or a flathead or whatever uh you can 2644 01:35:37,189 --> 01:35:35,460 so those are about 100 100 to 150 2645 01:35:40,250 --> 01:35:37,199 million years of evolutionary distance 2646 01:35:43,550 --> 01:35:40,260 and you can do it you know within within 2647 01:35:45,110 --> 01:35:43,560 a few days just by um by by perturbing 2648 01:35:47,689 --> 01:35:45,120 that electrical circuit so that it lands 2649 01:35:50,330 --> 01:35:47,699 in the wrong space and then outside of 2650 01:35:52,250 --> 01:35:50,340 that there are regions that don't belong 2651 01:35:54,169 --> 01:35:52,260 to planaria at all so planaria are 2652 01:35:56,270 --> 01:35:54,179 normally nice and flat we can make we've 2653 01:35:58,010 --> 01:35:56,280 made planarians that are they look like 2654 01:35:59,450 --> 01:35:58,020 a they are cylinder like like a ski cap 2655 01:36:02,090 --> 01:35:59,460 you know they become like a like a like 2656 01:36:04,070 --> 01:36:02,100 a hemisphere or really weird ones that 2657 01:36:05,510 --> 01:36:04,080 are spiky they're they're like a ball 2658 01:36:07,970 --> 01:36:05,520 with spikes on it they're all kinds of 2659 01:36:11,090 --> 01:36:07,980 other uh regions in that space that you 2660 01:36:13,189 --> 01:36:11,100 can that you can push them to uh and so 2661 01:36:15,229 --> 01:36:13,199 those are new those are not species that 2662 01:36:17,330 --> 01:36:15,239 they diverge from those are no one's 2663 01:36:18,649 --> 01:36:17,340 ever said to my knowledge that's yes 2664 01:36:19,910 --> 01:36:18,659 there's no such there are no such 2665 01:36:21,350 --> 01:36:19,920 species 2666 01:36:22,729 --> 01:36:21,360 um it's easier to you know and we've 2667 01:36:25,550 --> 01:36:22,739 done this in frog too you can you can 2668 01:36:27,410 --> 01:36:25,560 push tadpoles to make it to look like 2669 01:36:29,270 --> 01:36:27,420 those of other species 2670 01:36:30,709 --> 01:36:29,280 um or you can make you know I mean 2671 01:36:32,930 --> 01:36:30,719 that's a whole interesting thing for 2672 01:36:34,669 --> 01:36:32,940 evolution anyway right what one species 2673 01:36:36,770 --> 01:36:34,679 birth defect is a pretty is a perfectly 2674 01:36:39,169 --> 01:36:36,780 reasonable different species so we can 2675 01:36:42,590 --> 01:36:39,179 make we can make tadpoles with a rounded 2676 01:36:44,030 --> 01:36:42,600 tail which for a xenopus tadpole is a 2677 01:36:46,729 --> 01:36:44,040 terrible Tale But for zebrafish that's 2678 01:36:49,310 --> 01:36:46,739 exactly the right tale so you can sort 2679 01:36:51,610 --> 01:36:49,320 of Imagine imagine right Evolution uh 2680 01:36:53,629 --> 01:36:51,620 manipulating the different information 2681 01:36:55,010 --> 01:36:53,639 processing whether whether by the 2682 01:36:57,410 --> 01:36:55,020 bioelectrical circuits or other other 2683 01:37:00,229 --> 01:36:57,420 Machinery uh that help the system 2684 01:37:01,810 --> 01:37:00,239 explore that morphe space and you know 2685 01:37:05,870 --> 01:37:01,820 start to 2686 01:37:07,550 --> 01:37:05,880 from from whatever the you know that 2687 01:37:09,709 --> 01:37:07,560 speciation is moving away from your 2688 01:37:12,350 --> 01:37:09,719 standard attractor that you usually land 2689 01:37:15,410 --> 01:37:12,360 on how does this relate to intelligence 2690 01:37:17,390 --> 01:37:15,420 well intelligence is the ability to make 2691 01:37:19,129 --> 01:37:17,400 models and and usually in the service of 2692 01:37:22,310 --> 01:37:19,139 control at least that's the way I would 2693 01:37:24,350 --> 01:37:22,320 uh explain intelligence 2694 01:37:26,270 --> 01:37:24,360 there are other definitions but it's the 2695 01:37:27,350 --> 01:37:26,280 simplest one that I found it also 2696 01:37:29,209 --> 01:37:27,360 accounts for the fact that many 2697 01:37:31,550 --> 01:37:29,219 intelligent people are not very good at 2698 01:37:33,290 --> 01:37:31,560 getting things done uh that's it's 2699 01:37:36,110 --> 01:37:33,300 basically an intelligence and goal 2700 01:37:38,510 --> 01:37:36,120 rationality are support orthogonal 2701 01:37:41,750 --> 01:37:38,520 and excessive intelligence is often a 2702 01:37:44,090 --> 01:37:41,760 prosthesis for bad regulation have you 2703 01:37:47,270 --> 01:37:44,100 read the intelligence trap 2704 01:37:49,550 --> 01:37:47,280 no okay the author makes a similar case 2705 01:37:51,290 --> 01:37:49,560 and he's coming on shortly essentially 2706 01:37:53,209 --> 01:37:51,300 saying that there are certain traps that 2707 01:37:55,610 --> 01:37:53,219 people with high IQs have that are not 2708 01:37:58,070 --> 01:37:55,620 beneficial for them as biological beings 2709 01:37:59,810 --> 01:37:58,080 they're mainly cognitive biases so for 2710 01:38:01,729 --> 01:37:59,820 instance it's extremely interesting so 2711 01:38:03,530 --> 01:38:01,739 let's just give one of the biases to say 2712 01:38:05,450 --> 01:38:03,540 you're either liberal biased or you're 2713 01:38:07,250 --> 01:38:05,460 conservative biased and then you were to 2714 01:38:08,990 --> 01:38:07,260 give a test where there's some data that 2715 01:38:10,970 --> 01:38:09,000 says that on the surface it shows that 2716 01:38:13,790 --> 01:38:10,980 the data shows that gun control prevents 2717 01:38:15,649 --> 01:38:13,800 gun violence well the Liberals are more 2718 01:38:17,629 --> 01:38:15,659 likely to say yes this data does show 2719 01:38:19,070 --> 01:38:17,639 that but if you're conservative you're 2720 01:38:20,870 --> 01:38:19,080 more likely to find oh actually the 2721 01:38:23,870 --> 01:38:20,880 subtleties in the data show that gun 2722 01:38:25,129 --> 01:38:23,880 control increases gun violence and then 2723 01:38:26,510 --> 01:38:25,139 they thought okay well let's just switch 2724 01:38:28,370 --> 01:38:26,520 this to make it such that The 2725 01:38:31,010 --> 01:38:28,380 Superficial data suggests that gun 2726 01:38:32,390 --> 01:38:31,020 control increases violence you need to 2727 01:38:33,890 --> 01:38:32,400 look at the data carefully to show that 2728 01:38:35,209 --> 01:38:33,900 it actually prevents violence well the 2729 01:38:37,149 --> 01:38:35,219 conservatives in that case would be more 2730 01:38:39,590 --> 01:38:37,159 quickly to say oh look the gun control 2731 01:38:41,810 --> 01:38:39,600 increases violence and the Liberals 2732 01:38:43,010 --> 01:38:41,820 would find the the loophole well that's 2733 01:38:45,229 --> 01:38:43,020 one of the reasons why I don't mind 2734 01:38:47,629 --> 01:38:45,239 interviewing people who are biased 2735 01:38:49,970 --> 01:38:47,639 because to me they're more able to find 2736 01:38:52,970 --> 01:38:49,980 a justification for something that that 2737 01:38:55,010 --> 01:38:52,980 may be true but I or and others are so 2738 01:38:56,750 --> 01:38:55,020 well we all have our own biases we're so 2739 01:38:59,209 --> 01:38:56,760 inclined in some other direction that we 2740 01:39:00,350 --> 01:38:59,219 just we're blind to it but anyway the 2741 01:39:02,270 --> 01:39:00,360 point is to affirm what you're saying 2742 01:39:04,370 --> 01:39:02,280 yosha okay so I know Michael has a hard 2743 01:39:07,310 --> 01:39:04,380 cut off at 2PM so I want to ask the 2744 01:39:09,530 --> 01:39:07,320 question for AGI that is artificial 2745 01:39:11,810 --> 01:39:09,540 general intelligence it seems as though 2746 01:39:14,689 --> 01:39:11,820 we're far away or that our current 2747 01:39:16,669 --> 01:39:14,699 methods of machine learning and what we 2748 01:39:18,530 --> 01:39:16,679 learn in Neuroscience or or what we 2749 01:39:20,209 --> 01:39:18,540 learn in computer science is something 2750 01:39:22,129 --> 01:39:20,219 that we're missing some paradigm shift 2751 01:39:23,390 --> 01:39:22,139 or we're missing some new techniques is 2752 01:39:25,189 --> 01:39:23,400 there something from Michael's work 2753 01:39:26,750 --> 01:39:25,199 Yoshi I'm asking you this and then 2754 01:39:28,189 --> 01:39:26,760 Michael please respond is there 2755 01:39:30,169 --> 01:39:28,199 something from Michael's work that you 2756 01:39:33,709 --> 01:39:30,179 think can be applied to the development 2757 01:39:35,450 --> 01:39:33,719 of AGI if such a creature mind can exist 2758 01:39:37,070 --> 01:39:35,460 because there are some arguments against 2759 01:39:38,990 --> 01:39:37,080 it so first of all I don't know how far 2760 01:39:40,490 --> 01:39:39,000 we are for the HEI it could be that the 2761 01:39:41,750 --> 01:39:40,500 existing private names are sufficient to 2762 01:39:43,850 --> 01:39:41,760 brute force it 2763 01:39:45,470 --> 01:39:43,860 but we don't know that yet right so 2764 01:39:48,050 --> 01:39:45,480 we're going to find out in the next few 2765 01:39:49,550 --> 01:39:48,060 months uh but it could also be that we 2766 01:39:51,830 --> 01:39:49,560 need to rewrite the stack to build 2767 01:39:53,390 --> 01:39:51,840 systems that work in real time that are 2768 01:39:56,090 --> 01:39:53,400 entangled with the environment that can 2769 01:39:58,370 --> 01:39:56,100 build uh shared representations with the 2770 01:40:00,770 --> 01:39:58,380 environment and uh that we need to 2771 01:40:02,450 --> 01:40:00,780 rewrite the stack and there are actually 2772 01:40:04,490 --> 01:40:02,460 a number of questions that I'd like to 2773 01:40:07,610 --> 01:40:04,500 ask Michael 2774 01:40:09,709 --> 01:40:07,620 um what uh I noticed that Michael is 2775 01:40:11,750 --> 01:40:09,719 wisely reluctant to use certain words 2776 01:40:13,010 --> 01:40:11,760 like Consciousness a lot and it's 2777 01:40:14,750 --> 01:40:13,020 because a lot of people are very 2778 01:40:16,189 --> 01:40:14,760 opinionated about what these concepts 2779 01:40:18,470 --> 01:40:16,199 mean and you first have to deal with 2780 01:40:20,090 --> 01:40:18,480 these opinions before you come down to 2781 01:40:21,830 --> 01:40:20,100 saying oh here I have the following 2782 01:40:24,169 --> 01:40:21,840 proposal for implementing reflexive 2783 01:40:27,590 --> 01:40:24,179 attention as a tool to form coherence 2784 01:40:29,330 --> 01:40:27,600 and a representation and this leads to 2785 01:40:30,470 --> 01:40:29,340 the same phenomena as what you call 2786 01:40:33,290 --> 01:40:30,480 consciousness 2787 01:40:34,790 --> 01:40:33,300 right so uh that is is a detailed 2788 01:40:36,470 --> 01:40:34,800 discussion maybe you don't want to have 2789 01:40:37,970 --> 01:40:36,480 that discussion in every Foreman rather 2790 01:40:40,490 --> 01:40:37,980 than uh that and then having this 2791 01:40:42,470 --> 01:40:40,500 discussion you may be looking at uh how 2792 01:40:44,810 --> 01:40:42,480 to create coherence using a reflexive 2793 01:40:47,330 --> 01:40:44,820 attention process that makes a real-time 2794 01:40:48,890 --> 01:40:47,340 model of what it's attending to and the 2795 01:40:51,530 --> 01:40:48,900 fact that it's attending to it so it 2796 01:40:54,830 --> 01:40:51,540 remains coherent but for itself so this 2797 01:40:56,810 --> 01:40:54,840 is a concrete thing but uh I wonder how 2798 01:40:58,490 --> 01:40:56,820 to implement this in a self-organized 2799 01:41:00,950 --> 01:40:58,500 fashion if the substrate that you have 2800 01:41:04,250 --> 01:41:00,960 are individual agents and there is a 2801 01:41:07,430 --> 01:41:04,260 similarity here between societies and 2802 01:41:09,970 --> 01:41:07,440 brains and social networks 2803 01:41:12,229 --> 01:41:09,980 that is uh if you have 2804 01:41:13,370 --> 01:41:12,239 self-interested agents in a way that try 2805 01:41:15,290 --> 01:41:13,380 to survive 2806 01:41:17,330 --> 01:41:15,300 and that get their rewards from other 2807 01:41:19,189 --> 01:41:17,340 agents that are similar to them 2808 01:41:22,189 --> 01:41:19,199 structurally 2809 01:41:23,870 --> 01:41:22,199 and and they have the capacity to learn 2810 01:41:27,649 --> 01:41:23,880 to some degree 2811 01:41:30,229 --> 01:41:27,659 and that capacity is sufficient so they 2812 01:41:34,430 --> 01:41:30,239 can in the aggregate learn arbitrary 2813 01:41:37,129 --> 01:41:34,440 programs arbitrary computable functions 2814 01:41:38,930 --> 01:41:37,139 and it's efficient enough so they can 2815 01:41:42,770 --> 01:41:38,940 Converge on the functions that they need 2816 01:41:44,149 --> 01:41:42,780 to to as a group reap rewards that apply 2817 01:41:46,189 --> 01:41:44,159 to the whole group because they have a 2818 01:41:47,750 --> 01:41:46,199 shared Destiny like the poor little 2819 01:41:49,250 --> 01:41:47,760 cells that are locked in the same skull 2820 01:41:52,430 --> 01:41:49,260 and they are all going to die together 2821 01:41:54,169 --> 01:41:52,440 if they up so they have to get 2822 01:41:56,570 --> 01:41:54,179 along they have to form an organization 2823 01:41:58,790 --> 01:41:56,580 that is Distributing rewards among each 2824 01:42:01,729 --> 01:41:58,800 other and this gives us a search space 2825 01:42:04,250 --> 01:42:01,739 for possible systems that can exist and 2826 01:42:08,209 --> 01:42:04,260 the search space is mostly given I think 2827 01:42:09,830 --> 01:42:08,219 by the minimal agent that is able to 2828 01:42:11,090 --> 01:42:09,840 learn how to distribute rewards 2829 01:42:13,609 --> 01:42:11,100 efficiently 2830 01:42:15,649 --> 01:42:13,619 while doing something useful using these 2831 01:42:17,689 --> 01:42:15,659 rewards to change how you do something 2832 01:42:20,209 --> 01:42:17,699 useful so you have an emerging form of 2833 01:42:22,129 --> 01:42:20,219 governance in these systems there's not 2834 01:42:24,050 --> 01:42:22,139 some centralized control that is imposed 2835 01:42:25,550 --> 01:42:24,060 on the system from the outside as an 2836 01:42:28,310 --> 01:42:25,560 existing machine learning approaches and 2837 01:42:30,649 --> 01:42:28,320 AI approaches but this is this only is 2838 01:42:32,750 --> 01:42:30,659 an emergent pattern in the interactions 2839 01:42:35,270 --> 01:42:32,760 between the individual small units small 2840 01:42:37,070 --> 01:42:35,280 reinforcement learning agents and this 2841 01:42:39,169 --> 01:42:37,080 control architecture leads to 2842 01:42:41,030 --> 01:42:39,179 hierarchical government it's not fully 2843 01:42:42,770 --> 01:42:41,040 decentralized in any way there are 2844 01:42:44,390 --> 01:42:42,780 centralized structures that distribute 2845 01:42:46,729 --> 01:42:44,400 rewards for instance via the 2846 01:42:48,649 --> 01:42:46,739 dopaminergic system and very centralized 2847 01:42:50,629 --> 01:42:48,659 top-down Manner and that's because every 2848 01:42:52,490 --> 01:42:50,639 regulation has an optimal layer where it 2849 01:42:54,649 --> 01:42:52,500 needs to take place some stuff needs to 2850 01:42:56,450 --> 01:42:54,659 be decided very high up some stuff needs 2851 01:42:58,430 --> 01:42:56,460 to be optimally regulated very low down 2852 01:43:00,410 --> 01:42:58,440 depending on the incentives game 2853 01:43:02,750 --> 01:43:00,420 theoretically a government is an agent 2854 01:43:06,229 --> 01:43:02,760 that imposes an offset on your payoff 2855 01:43:08,270 --> 01:43:06,239 metrics to make your Nash equilibrium 2856 01:43:10,189 --> 01:43:08,280 compatible with the globally best 2857 01:43:12,530 --> 01:43:10,199 outcome 2858 01:43:14,330 --> 01:43:12,540 right so to to do this you need to have 2859 01:43:16,070 --> 01:43:14,340 agents that are sensitive to rewards 2860 01:43:18,950 --> 01:43:16,080 it's super interesting to think about 2861 01:43:20,870 --> 01:43:18,960 these reward infrastructures Elon Musk 2862 01:43:22,790 --> 01:43:20,880 has bought Twitter I think because he 2863 01:43:24,830 --> 01:43:22,800 has realized that Twitter is the network 2864 01:43:27,229 --> 01:43:24,840 of among all the social networks that is 2865 01:43:29,270 --> 01:43:27,239 closest to a global brain 2866 01:43:30,649 --> 01:43:29,280 it's totally mind-blowing to realize 2867 01:43:33,169 --> 01:43:30,659 that he basically trades a bunch of 2868 01:43:36,290 --> 01:43:33,179 frothy stock for the opportunity to 2869 01:43:38,270 --> 01:43:36,300 become Pope pope of a religion that has 2870 01:43:40,010 --> 01:43:38,280 more active participants than 2871 01:43:42,290 --> 01:43:40,020 Catholicism even right daily 2872 01:43:44,270 --> 01:43:42,300 practitioning people who enter this 2873 01:43:45,709 --> 01:43:44,280 church and think together and it's a 2874 01:43:46,970 --> 01:43:45,719 thing that is completely incoherent at 2875 01:43:49,129 --> 01:43:46,980 this point almost and completely 2876 01:43:50,450 --> 01:43:49,139 incorrect the bubbles of sentience but 2877 01:43:52,010 --> 01:43:50,460 for the most part this thing is just 2878 01:43:54,229 --> 01:43:52,020 screeching at itself 2879 01:43:56,149 --> 01:43:54,239 and now the SD question can we fix the 2880 01:43:57,410 --> 01:43:56,159 incentives of Twitter to turn it into a 2881 01:44:01,910 --> 01:43:57,420 global brain 2882 01:44:03,770 --> 01:44:01,920 believes that this is the case and 2883 01:44:05,510 --> 01:44:03,780 that's the experiment that he is trying 2884 01:44:07,250 --> 01:44:05,520 to do which makes me super excited right 2885 01:44:09,530 --> 01:44:07,260 this might fail is a very big chance 2886 01:44:11,330 --> 01:44:09,540 that it fails but there is also the 2887 01:44:13,189 --> 01:44:11,340 chance that we get the global brain that 2888 01:44:15,830 --> 01:44:13,199 we get emerging collective intelligence 2889 01:44:17,209 --> 01:44:15,840 it is working in real time using the 2890 01:44:19,970 --> 01:44:17,219 internet in a way that didn't exist 2891 01:44:22,250 --> 01:44:19,980 before so super fascinating thing that 2892 01:44:24,109 --> 01:44:22,260 might happen here and it's fascinating 2893 01:44:26,870 --> 01:44:24,119 that very few people are seeing this 2894 01:44:29,270 --> 01:44:26,880 that Elon Musk is crazy enough to to 2895 01:44:31,430 --> 01:44:29,280 spend 44 billion dollars on that 2896 01:44:32,629 --> 01:44:31,440 experiment just because he can and has 2897 01:44:34,550 --> 01:44:32,639 nothing else to do with things it's 2898 01:44:36,470 --> 01:44:34,560 meaningful to do it more meaningful than 2899 01:44:41,090 --> 01:44:36,480 having so much money in the bank right 2900 01:44:43,129 --> 01:44:41,100 so this makes me interested in this test 2901 01:44:44,870 --> 01:44:43,139 bed for rewards and this is something 2902 01:44:46,729 --> 01:44:44,880 that translates into the way in which 2903 01:44:48,530 --> 01:44:46,739 society is organized because social 2904 01:44:50,390 --> 01:44:48,540 media is not different from society not 2905 01:44:52,310 --> 01:44:50,400 separate from it problem of governing 2906 01:44:54,649 --> 01:44:52,320 social media is exactly the same thing 2907 01:44:56,330 --> 01:44:54,659 as governing a society you need a right 2908 01:44:58,129 --> 01:44:56,340 form of government you need a legal 2909 01:44:59,990 --> 01:44:58,139 system ultimately you need 2910 01:45:01,669 --> 01:45:00,000 representation and all these issues 2911 01:45:04,850 --> 01:45:01,679 right it's not just the moderation team 2912 01:45:06,109 --> 01:45:04,860 and the same thing is also true for the 2913 01:45:09,050 --> 01:45:06,119 brain what is the government of the 2914 01:45:11,090 --> 01:45:09,060 brain that emerges in what Gary Edelman 2915 01:45:13,550 --> 01:45:11,100 calls neural Darwinism among different 2916 01:45:15,410 --> 01:45:13,560 forms of organization in the mind until 2917 01:45:17,209 --> 01:45:15,420 you have a model of a self-organizing 2918 01:45:19,310 --> 01:45:17,219 agent that discovers that what it's 2919 01:45:20,870 --> 01:45:19,320 Computing is driving the behavior of an 2920 01:45:22,970 --> 01:45:20,880 agent in the real world and discovers a 2921 01:45:24,950 --> 01:45:22,980 first person perspective and so on how 2922 01:45:26,870 --> 01:45:24,960 does that work how can we get a system 2923 01:45:29,570 --> 01:45:26,880 that is looking for the right incentive 2924 01:45:32,930 --> 01:45:29,580 architecture and that is basically the 2925 01:45:35,330 --> 01:45:32,940 main topic where I I think that where 2926 01:45:37,189 --> 01:45:35,340 Michael's research is pointing from from 2927 01:45:40,550 --> 01:45:37,199 my perspective that is super interesting 2928 01:45:42,890 --> 01:45:40,560 we have this overlap between the looking 2929 01:45:47,570 --> 01:45:42,900 at cells and looking at the world and of 2930 01:45:51,350 --> 01:45:47,580 humans and animals and stuff in general 2931 01:45:54,169 --> 01:45:51,360 yeah yeah so super interesting um we so 2932 01:45:57,229 --> 01:45:54,179 so Chris fields and I are are working on 2933 01:45:59,350 --> 01:45:57,239 a model of of on a framework to 2934 01:46:01,370 --> 01:45:59,360 understand the the 2935 01:46:03,350 --> 01:46:01,380 where where 2936 01:46:05,689 --> 01:46:03,360 um Collective agents first come from 2937 01:46:08,450 --> 01:46:05,699 right oh well how Auto police is how do 2938 01:46:11,390 --> 01:46:08,460 they organize themselves and we've we've 2939 01:46:13,790 --> 01:46:11,400 we've we've got a model already about 2940 01:46:15,770 --> 01:46:13,800 this idea of of rewards and sells 2941 01:46:17,390 --> 01:46:15,780 rewarding other cells with with 2942 01:46:19,669 --> 01:46:17,400 neurotransmitters and things like this 2943 01:46:21,530 --> 01:46:19,679 to keep copies of themselves nearby 2944 01:46:23,750 --> 01:46:21,540 because they're the most predictable so 2945 01:46:25,250 --> 01:46:23,760 so this idea of reducing surprise well 2946 01:46:27,290 --> 01:46:25,260 what's the least surprising thing it's a 2947 01:46:29,030 --> 01:46:27,300 copy of yourself and so you can sort of 2948 01:46:31,669 --> 01:46:29,040 this with Chris calls it the Imperial 2949 01:46:34,370 --> 01:46:31,679 model of multicellularity but one thing 2950 01:46:37,729 --> 01:46:34,380 to really think about here is Imagine an 2951 01:46:39,290 --> 01:46:37,739 embryo this is a um an amniote embryo 2952 01:46:40,790 --> 01:46:39,300 let's say a human or or a bird or 2953 01:46:43,850 --> 01:46:40,800 something like that and what you have 2954 01:46:46,669 --> 01:46:43,860 there is you have a flat disk of fifty 2955 01:46:48,470 --> 01:46:46,679 to ten thousand fifty thousand cells and 2956 01:46:50,510 --> 01:46:48,480 when people look at it you say what is 2957 01:46:52,910 --> 01:46:50,520 that they say it's an embryo one one 2958 01:46:54,950 --> 01:46:52,920 embryo well the reason it's one embryo 2959 01:46:56,990 --> 01:46:54,960 is that under normal conditions what's 2960 01:47:00,649 --> 01:46:57,000 going to happen is that in this in this 2961 01:47:02,149 --> 01:47:00,659 disc one cell is symmetry breaking one 2962 01:47:03,830 --> 01:47:02,159 cell is going to decide that it's the 2963 01:47:05,750 --> 01:47:03,840 organizer it's going to do local 2964 01:47:07,070 --> 01:47:05,760 activation long range inhibition it's 2965 01:47:09,169 --> 01:47:07,080 going to tell all the other cells you're 2966 01:47:11,470 --> 01:47:09,179 not the organizer I'm the organizer and 2967 01:47:15,530 --> 01:47:11,480 as a result you get one special point 2968 01:47:17,930 --> 01:47:15,540 that uh begins uh the a process that's 2969 01:47:19,430 --> 01:47:17,940 going to walk through this amorphous 2970 01:47:21,109 --> 01:47:19,440 space and create a particular 2971 01:47:22,490 --> 01:47:21,119 large-scale structure with two eyes and 2972 01:47:25,129 --> 01:47:22,500 four legs and whatever else it's going 2973 01:47:27,590 --> 01:47:25,139 to have but here's the interesting thing 2974 01:47:29,870 --> 01:47:27,600 those cells that's not really one embryo 2975 01:47:32,030 --> 01:47:29,880 that's that's um a weird kind of 2976 01:47:34,070 --> 01:47:32,040 Freudian ocean of potentiality what I 2977 01:47:35,390 --> 01:47:34,080 mean by that is if you take and I did 2978 01:47:37,609 --> 01:47:35,400 this as a grad student you can take a 2979 01:47:39,530 --> 01:47:37,619 needle and you can put a little scratch 2980 01:47:41,629 --> 01:47:39,540 through that blastoderm put a little 2981 01:47:43,609 --> 01:47:41,639 scratch through it what will happen is 2982 01:47:45,410 --> 01:47:43,619 the cells on either side of that scratch 2983 01:47:47,390 --> 01:47:45,420 don't feel each other they don't hear 2984 01:47:49,250 --> 01:47:47,400 each other's signals so that symmetry 2985 01:47:51,770 --> 01:47:49,260 breaking process will happen twice once 2986 01:47:53,270 --> 01:47:51,780 on each end and then when it heals 2987 01:47:55,669 --> 01:47:53,280 together what you end up with is two 2988 01:47:57,830 --> 01:47:55,679 conjoined twins because because each 2989 01:48:00,050 --> 01:47:57,840 side organized an embryo and now you've 2990 01:48:03,169 --> 01:48:00,060 got two conjoined twins now many 2991 01:48:06,050 --> 01:48:03,179 interesting things happen there uh one 2992 01:48:08,510 --> 01:48:06,060 is that every cell is some other cells 2993 01:48:11,030 --> 01:48:08,520 in external environment so in order to 2994 01:48:13,729 --> 01:48:11,040 make an embryo you have to self-organize 2995 01:48:15,709 --> 01:48:13,739 A system that puts an arbitrary boundary 2996 01:48:17,270 --> 01:48:15,719 between itself and the outside world you 2997 01:48:19,310 --> 01:48:17,280 have to decide where do I end and the 2998 01:48:22,430 --> 01:48:19,320 world begins and it's not given to you 2999 01:48:24,050 --> 01:48:22,440 uh you know somehow um from outside for 3000 01:48:25,609 --> 01:48:24,060 a biological system every biological 3001 01:48:27,830 --> 01:48:25,619 system has to figure this out for itself 3002 01:48:29,149 --> 01:48:27,840 unlike modern robotics or whatever where 3003 01:48:30,470 --> 01:48:29,159 it's very clear here's where you are 3004 01:48:32,149 --> 01:48:30,480 here's where the world is these are your 3005 01:48:34,010 --> 01:48:32,159 reflectors these are your sensors here's 3006 01:48:35,270 --> 01:48:34,020 the boundary of the outside world living 3007 01:48:36,770 --> 01:48:35,280 things don't have any of that they have 3008 01:48:39,950 --> 01:48:36,780 to figure out all of this out from 3009 01:48:41,510 --> 01:48:39,960 scratch the benefit to being able to 3010 01:48:43,370 --> 01:48:41,520 figure it out from scratch having to 3011 01:48:46,010 --> 01:48:43,380 figure out from scratch is that you are 3012 01:48:47,570 --> 01:48:46,020 then compatible with all kinds of weird 3013 01:48:49,370 --> 01:48:47,580 initial conditions for example if I 3014 01:48:50,990 --> 01:48:49,380 separate you in half you can make two 3015 01:48:52,729 --> 01:48:51,000 you can make twins you don't you don't 3016 01:48:54,050 --> 01:48:52,739 have a failure you know a total failure 3017 01:48:55,609 --> 01:48:54,060 because now you have half the number of 3018 01:48:58,910 --> 01:48:55,619 cells you can make twins you can make 3019 01:49:00,590 --> 01:48:58,920 triplets but probably you know many more 3020 01:49:02,390 --> 01:49:00,600 than that so if you ask the question you 3021 01:49:04,850 --> 01:49:02,400 look at that um blasted room and you ask 3022 01:49:06,410 --> 01:49:04,860 how many individuals are there you 3023 01:49:07,790 --> 01:49:06,420 actually don't know it could be zero it 3024 01:49:10,910 --> 01:49:07,800 could be one it could be some small 3025 01:49:13,609 --> 01:49:10,920 number of individuals that process of 3026 01:49:15,530 --> 01:49:13,619 Auto releases has to happen and and and 3027 01:49:17,570 --> 01:49:15,540 here all the here are a number of things 3028 01:49:20,270 --> 01:49:17,580 that that are uniquely biological that 3029 01:49:22,669 --> 01:49:20,280 that I think relate to the kind of 3030 01:49:25,970 --> 01:49:22,679 flexibility plasticity uh that you need 3031 01:49:27,169 --> 01:49:25,980 for for for AGI in whatever space it 3032 01:49:30,109 --> 01:49:27,179 doesn't have to be the same space that 3033 01:49:32,149 --> 01:49:30,119 we work in but your your boundaries are 3034 01:49:33,530 --> 01:49:32,159 not set for you by an outside Creator 3035 01:49:34,850 --> 01:49:33,540 you have to figure out where your 3036 01:49:37,310 --> 01:49:34,860 boundaries are where is the outside 3037 01:49:39,229 --> 01:49:37,320 world so you make hypotheses about where 3038 01:49:41,030 --> 01:49:39,239 you end and where the world begins you 3039 01:49:42,890 --> 01:49:41,040 don't actually know what your structure 3040 01:49:44,629 --> 01:49:42,900 is kind of like Bond guards robots from 3041 01:49:45,950 --> 01:49:44,639 2006 where they didn't know their 3042 01:49:47,689 --> 01:49:45,960 structure and they had to make 3043 01:49:49,189 --> 01:49:47,699 hypotheses about well do I have wheels 3044 01:49:52,850 --> 01:49:49,199 do I have legs what do I have and then 3045 01:49:55,129 --> 01:49:52,860 make a model based on basically babbling 3046 01:49:56,750 --> 01:49:55,139 right like the way that babies babble so 3047 01:49:58,729 --> 01:49:56,760 so you have to figure out you have to 3048 01:50:00,169 --> 01:49:58,739 make a model of of where the boundary is 3049 01:50:02,629 --> 01:50:00,179 you have to make a model of what your 3050 01:50:04,850 --> 01:50:02,639 structure is you are energy limited 3051 01:50:06,890 --> 01:50:04,860 which most the most Ai and Robotics 3052 01:50:09,649 --> 01:50:06,900 nowadays are not when your energy and 3053 01:50:11,629 --> 01:50:09,659 time limited it means that you cannot 3054 01:50:13,430 --> 01:50:11,639 pay attention to everything you are 3055 01:50:14,930 --> 01:50:13,440 forced to coarse grain in some way and 3056 01:50:16,790 --> 01:50:14,940 lose a lot of information and compress 3057 01:50:19,129 --> 01:50:16,800 it down so you have to you have to 3058 01:50:20,810 --> 01:50:19,139 choose a lens a coarse graining lens on 3059 01:50:22,550 --> 01:50:20,820 the world and figure out how you're 3060 01:50:25,550 --> 01:50:22,560 going to represent things 3061 01:50:27,470 --> 01:50:25,560 um uh and and all of this has to and and 3062 01:50:29,470 --> 01:50:27,480 there are many more things that we could 3063 01:50:31,970 --> 01:50:29,480 talk about but all of these things are 3064 01:50:33,890 --> 01:50:31,980 self-constructions from the from the 3065 01:50:35,870 --> 01:50:33,900 very beginning and and then and then you 3066 01:50:37,970 --> 01:50:35,880 have to you have to uh you start to act 3067 01:50:40,010 --> 01:50:37,980 in various in various spaces which again 3068 01:50:41,450 --> 01:50:40,020 are not predefined for you you have to 3069 01:50:43,250 --> 01:50:41,460 solve problems that are metabolic 3070 01:50:45,410 --> 01:50:43,260 physiological anatomical maybe 3071 01:50:48,290 --> 01:50:45,420 behavioral if you have muscles 3072 01:50:50,090 --> 01:50:48,300 um but but nobody's telling nobody's 3073 01:50:51,830 --> 01:50:50,100 defining the space for you 3074 01:50:53,330 --> 01:50:51,840 um for example if you're a bacterium a 3075 01:50:54,830 --> 01:50:53,340 Chris field zupo points this out if 3076 01:50:57,649 --> 01:50:54,840 you're a bacterium and you're in some 3077 01:50:59,510 --> 01:50:57,659 sort of chemical gradient you want to 3078 01:51:01,070 --> 01:50:59,520 increase the amount of sugar in your 3079 01:51:02,750 --> 01:51:01,080 environment you could act in 3080 01:51:05,390 --> 01:51:02,760 three-dimensional Space by physically 3081 01:51:07,189 --> 01:51:05,400 swimming up the gradient or you can act 3082 01:51:08,629 --> 01:51:07,199 in transcriptional Space by turning on 3083 01:51:10,609 --> 01:51:08,639 other genes that are better at 3084 01:51:12,050 --> 01:51:10,619 converting whatever sugar happens to be 3085 01:51:13,850 --> 01:51:12,060 around and that solves your your 3086 01:51:16,010 --> 01:51:13,860 metabolic problem instead of right so 3087 01:51:18,350 --> 01:51:16,020 you have these hybrid problem spaces so 3088 01:51:20,330 --> 01:51:18,360 all of this I think what what 3089 01:51:21,709 --> 01:51:20,340 contributes in a strong sense to all the 3090 01:51:23,930 --> 01:51:21,719 things that that we were just talking 3091 01:51:25,970 --> 01:51:23,940 about is the fact that everything is in 3092 01:51:27,590 --> 01:51:25,980 in biology is self-constructed from the 3093 01:51:28,729 --> 01:51:27,600 beginning you can't rely on you don't 3094 01:51:30,590 --> 01:51:28,739 know ahead of time when you're a new 3095 01:51:32,930 --> 01:51:30,600 creature Born Into the world and we have 3096 01:51:34,189 --> 01:51:32,940 many I have many examples of of this 3097 01:51:35,689 --> 01:51:34,199 kind of stuff you don't know how many 3098 01:51:38,149 --> 01:51:35,699 cells you have how big your cells are 3099 01:51:39,890 --> 01:51:38,159 you can't count on any of the priors so 3100 01:51:42,830 --> 01:51:39,900 you have this like weird thing that 3101 01:51:45,109 --> 01:51:42,840 Evolution makes these these machines 3102 01:51:46,669 --> 01:51:45,119 that don't take the past history too 3103 01:51:49,070 --> 01:51:46,679 seriously it doesn't over train on them 3104 01:51:50,930 --> 01:51:49,080 it makes problem-solving machines that 3105 01:51:53,209 --> 01:51:50,940 use whatever Hardware you have this is 3106 01:51:55,250 --> 01:51:53,219 why we can make weird chimeras and and 3107 01:51:57,770 --> 01:51:55,260 and cyborgs and and you can mix things 3108 01:52:00,830 --> 01:51:57,780 and mix and match the biology in every 3109 01:52:03,050 --> 01:52:00,840 in every way with other living things or 3110 01:52:04,729 --> 01:52:03,060 with with non-living things because all 3111 01:52:06,350 --> 01:52:04,739 of this is interoperable because it does 3112 01:52:08,270 --> 01:52:06,360 not make assumptions about what you have 3113 01:52:10,010 --> 01:52:08,280 to have it tries to solve whatever 3114 01:52:13,070 --> 01:52:10,020 problem it's given it plays the hands 3115 01:52:16,070 --> 01:52:13,080 that it's dealt and um that that that 3116 01:52:19,010 --> 01:52:16,080 results in uh that assumption that you 3117 01:52:20,570 --> 01:52:19,020 cannot uh you cannot trust what you come 3118 01:52:22,970 --> 01:52:20,580 into the world with you cannot assume 3119 01:52:24,770 --> 01:52:22,980 that the hardware is what it is it gives 3120 01:52:27,050 --> 01:52:24,780 rise to a lot of that intelligence I 3121 01:52:28,729 --> 01:52:27,060 think and a lot of that plasticity so if 3122 01:52:31,669 --> 01:52:28,739 you translate this into necessary 3123 01:52:34,490 --> 01:52:31,679 insufficient conditions what seems to be 3124 01:52:37,970 --> 01:52:34,500 necessary for the emergence of general 3125 01:52:41,870 --> 01:52:37,980 intelligence in bunch of cells or units 3126 01:52:44,030 --> 01:52:41,880 is that basically each of them is a 3127 01:52:46,790 --> 01:52:44,040 small agent which means it's able to 3128 01:52:49,310 --> 01:52:46,800 behave with an expectation of minimizing 3129 01:52:50,510 --> 01:52:49,320 future Target value deviations so it 3130 01:52:52,430 --> 01:52:50,520 learns that the configurations 3131 01:52:55,550 --> 01:52:52,440 environment that signal anticipated 3132 01:52:57,229 --> 01:52:55,560 reward next thing these units need to be 3133 01:52:58,910 --> 01:52:57,239 not just agents that need to be 3134 01:53:01,189 --> 01:52:58,920 connected to each other 3135 01:53:03,229 --> 01:53:01,199 and they need to get their Rewards or 3136 01:53:04,729 --> 01:53:03,239 proxy rewards something that allows them 3137 01:53:06,830 --> 01:53:04,739 to anticipate whether the organism is 3138 01:53:09,830 --> 01:53:06,840 going to feed them in the future from 3139 01:53:12,229 --> 01:53:09,840 other units that also adaptive 3140 01:53:14,149 --> 01:53:12,239 so you need multiple message types and 3141 01:53:17,750 --> 01:53:14,159 the ability to recognize and send them 3142 01:53:21,169 --> 01:53:19,430 uh what else do you need you need enough 3143 01:53:23,810 --> 01:53:21,179 of them of course 3144 01:53:25,490 --> 01:53:23,820 what what's not clear to me is how 3145 01:53:27,350 --> 01:53:25,500 deterministic do the units need to be 3146 01:53:29,030 --> 01:53:27,360 how much memory do they need to be or 3147 01:53:31,149 --> 01:53:29,040 which way how much State can they store 3148 01:53:33,410 --> 01:53:31,159 how much uh 3149 01:53:35,629 --> 01:53:33,420 how deep in time does the indeed 3150 01:53:37,609 --> 01:53:35,639 recollection need to go and how much 3151 01:53:40,070 --> 01:53:37,619 forward in time do they need to be able 3152 01:53:43,609 --> 01:53:40,080 to form expectations so basically how 3153 01:53:45,169 --> 01:53:43,619 large is this activation front that they 3154 01:53:47,450 --> 01:53:45,179 can or this or the shape of the 3155 01:53:49,609 --> 01:53:47,460 distribution that they can learn 3156 01:53:50,810 --> 01:53:49,619 and have to learn to make this whole 3157 01:53:53,450 --> 01:53:50,820 thing happen 3158 01:53:56,330 --> 01:53:53,460 and so basically the conditions that are 3159 01:53:58,129 --> 01:53:56,340 necessary are relatively simple 3160 01:54:00,229 --> 01:53:58,139 if you just wait for long enough and get 3161 01:54:02,810 --> 01:54:00,239 a search assistance to percolate I 3162 01:54:05,510 --> 01:54:02,820 imagine that the compound agency will at 3163 01:54:07,609 --> 01:54:05,520 some level emerge on the system just in 3164 01:54:09,950 --> 01:54:07,619 the competition of 3165 01:54:11,930 --> 01:54:09,960 um possibilities in the same way as 3166 01:54:13,250 --> 01:54:11,940 emerging agency has emerged on Twitter 3167 01:54:15,590 --> 01:54:13,260 in a way with 3168 01:54:17,990 --> 01:54:15,600 um devoke religion in a way that people 3169 01:54:20,090 --> 01:54:18,000 who are starting to shift around their 3170 01:54:22,250 --> 01:54:20,100 behavior to maximize likes and retweets 3171 01:54:24,770 --> 01:54:22,260 and there was no external reward that 3172 01:54:26,810 --> 01:54:24,780 was given on Twitter so as a result a 3173 01:54:28,669 --> 01:54:26,820 local structure emerged a local agency 3174 01:54:31,370 --> 01:54:28,679 that was Shifting the rewards by itself 3175 01:54:33,350 --> 01:54:31,380 an emerging causal structure that was in 3176 01:54:35,950 --> 01:54:33,360 some sense in Dawn what causation 3177 01:54:39,250 --> 01:54:35,960 going to organize groups of people into 3178 01:54:41,570 --> 01:54:39,260 a behavioral things it's really 3179 01:54:44,270 --> 01:54:41,580 interesting to look at better as 3180 01:54:46,729 --> 01:54:44,280 something like a mind at some level 3181 01:54:47,870 --> 01:54:46,739 right it's working slower but it would 3182 01:54:50,030 --> 01:54:47,880 probably be possible to make a 3183 01:54:51,890 --> 01:54:50,040 simulation of these Dynamics in a more 3184 01:54:53,750 --> 01:54:51,900 abstract way and to use this for 3185 01:54:56,450 --> 01:54:53,760 arbitrary problem solving 3186 01:54:58,609 --> 01:54:56,460 and so what would an experiment look 3187 01:55:00,530 --> 01:54:58,619 like in which we start with these 3188 01:55:02,990 --> 01:55:00,540 necessary conditions and narrow down the 3189 01:55:06,050 --> 01:55:03,000 sufficient conditions yeah 3190 01:55:07,669 --> 01:55:06,060 yeah yeah very very right on and that's 3191 01:55:09,950 --> 01:55:07,679 I mean yeah we're doing some of that 3192 01:55:11,990 --> 01:55:09,960 stuff uh some of that kind of modeling I 3193 01:55:14,090 --> 01:55:12,000 apologize I've got a

3207 01:55:41,450 --> 01:55:39,239 also I recently found out that external 3208 01:55:43,550 --> 01:55:41,460 links count plenty toward the algorithm 3209 01:55:45,770 --> 01:55:43,560 which means that when you share on 3210 01:55:47,930 --> 01:55:45,780 Twitter on Facebook on Reddit 3211 01:55:49,729 --> 01:55:47,940 Etc it shows YouTube that people are 3212 01:55:51,830 --> 01:55:49,739 talking about this outside of YouTube 3213 01:55:53,689 --> 01:55:51,840 which in turn greatly AIDS the 3214 01:55:55,310 --> 01:55:53,699 Distribution on YouTube as well if you'd 3215 01:55:57,609 --> 01:55:55,320 like to support more conversations like 3216 01:55:59,689 --> 01:55:57,619 this then do consider visiting 3217 01:56:01,970 --> 01:55:59,699 theoriesofeverything.org again it's 3218 01:56:04,430 --> 01:56:01,980 support from the sponsors and you that 3219 01:56:06,109 --> 01:56:04,440 allow me to work on top full time you 3220 01:56:08,149 --> 01:56:06,119 get early access to ad-free audio 3221 01:56:10,250 --> 01:56:08,159 episodes there as well every dollar 3222 01:56:12,290 --> 01:56:10,260 helps far more than you may think either
