Bullshit!
The only way to work under that kind of pressure is saturation, or containment, as in a
submarine type vehicle.
Prolonged saturation is out.

Maximum record depth is 2000 feet in an "ADS" suit.
Maximum recorded depth with SCUBA is 1083 feet.
ADS suits are practical (on Earth), SCUBA is not.
However, nothing will work on Venus. The ADS suit is
rugged but is not designed for chemical or heat resistance.
The denaturing of the proteins in the human body is an extreme
risk. There is no practical way to support the suit (currently
operates like a tethered submersible).
SCUBA will be fatal instantly.
In fact, anything sent there dies. Machine or biological.
Quite so.
He can't seem to understand the simplest concepts, like, a bottle, compressed to 1300
psi, on the surface of Venus, is an empty bottle, as far as breathing from it is
concerned.
He has got dirigibles on the brain, and sees them, and some undefined, or at best, ill
defined, "composites", as the answer to everything.
The subject is a stupid "what if", anyway. Sort of like the crap you
would hear from a 6 year old.
True enough, although I have known such "what if" debates, to actually come up with
workable solutions, on occasion.
BradGuth, OTOH, isn't interested in actually working out "How to", he leaves that in the
hands of that great mysterious, "They", and sees all references to the difficulties that
need to be addressed, as negativity.
One can only assume that from his POV, only morons worry about practicalities.
Your continued inability to research past your extremely brown nose is
noted, as is your obvious incest mutated inability to deductively
think inside or much less outside of that cozy mainstream box of
yours.

“Abstract : Simulated dives were made with dogs to a depth equivalent
to 1000 feet of Sea water (305 meters). Sixteen of these animals
breathed a non-explosive hydrogen-oxygen mixture (hydrox) containing
no more than 3% oxygen, while 12 breathed gas mixtures containing
helium in place of hydrogen. In a number of dives, animals were
exposed to hydrogen continuously for between 96-100 hours, 48 of which
was spent at 1000 FSW. Extensive pre- and post-dive blood enzyme and
hematological studies were carried out. In addition lung, brain and
liver biopsies were carried out on selected animals. all such studies
showed no significant abnormalities. One dive employing helium and one
dive employing hydrogen proved fatal. In both instances, these
fatalities were due to volatile hydrocarbons present in a cylinder of
contaminated oxygen. All other animals survived the exposures. Indeed,
some animals made more than one dive. Three of these animals still
appear normal after 3 to 5 years post-dive. EEG studies showed no
residual post-dive abnormalities and no evidence of High Pressure
Nervous Syndrome while at 1000 FSW, although transient EEG
abnormalities were noted during hypoxia. Techniques were developed for
mixing hydrogen and oxygen in a non-explosive manner. The techniques
developed for the use of hydrox appear to be reasonably safe. For the
past eleven years, this laboratory has carried out over 645O hours of
hydrox exposure on animals including mice, rats, dogs, and man, and
has mixed approximately 200 cylinders of hydrox without an accident
related to the use of hydrogen.”
I’m sure there are any number of higher pressure tested examples of
complex biodiversity doing just fine and dandy at even 1% O2 and 99%
H2.
Gradual pressurization (say of applied over 100 days) and perhaps
somewhat minor physiological modifications would be required,
including an Ove-Glove composite suit and heat exchanging would be
required, along with a sufficient supply of frozen pizza and ice cold
beer.
