Once again, the distinction between correlation and causality must be
explained.
The human population has increased in correlation with technological
innovation. That *does not* mean that if there is a small population,
technology will vanish. Indeed, if the population were to start
dropping tomorrow, it would likely *stimulate* the development of
technology to replace labor.
First-world high-tech high-consumption living standards are perfectly
'sustainable' as long as there are few enough people.
I agree.  I suspect it would be far easier to create an
electric generator than to start over with stone age
technology.

After all, how many of us know how to chip stones so as to form
a proper stone age tool?  But lots of us know the fundamentals of
building a generator.

There are archaeologists who specialise in just this area--the best way to
make assorted flint tools with materials at hand (other stones, deer
antlers, etc).

Sure, but more of us can spin a copper loop in a magnetic field.

Where to get the copper?

That's the question. But there are two sci-fi scenarios to play with
here:

1) Post-apocalyptic Earth where everyone dresses like 19th century
street urchins, and there is all the material mess we've made to pick
over, in which case we go directly back to high tech, or at least
somewhere in the 20th century.

2) The more interesting one, in terms of paths and choices. Alens
abduct some of us and after obligatory probing drop us off on a
pristine Earth-identical  planet, with say a 2-year food supply. What
would you do---search for sources of flint for knapping, or go
directly to metal ores?  (If you really want glass arrowheads, we
could probably make them directly from sand and clay.)  Raise
livestock or go fishing?  Hydro or steam? ...

In either case, my original comment still works. If we are clever
enough to keep the population at a reasonable level, we would pretty
quickly be back to a comfortable (and sustainable) lifestyle.
