Nanotechnology and AI is resource intensive?

You haven't been paying attention. While slow going, we've had molecular moving parts for years. There were several versions
of a molecular memory that used a rotating ring molecule around a bar-like molecule to denote 1 or 0.
We're now building shapes and materials at the protein level, and often by proteins or protein-like mechanisms. Sometimes these
are for biological purposes, sometimes not at all.
After getting extremely good at imaging individual atoms and small and large molecules, we're now very good at pushing and
placing individual atoms. A good chunk of the supercomputing capacity right now is working on protein folding to both
understand and engineer molecular shapes and mechanisms.

He's wrong about flying cars, they're shipping next year. He's also wrong about flying being necessarily hard: there are dozens
(at least) of UAVs flying that are completely automatic. Most airliners land themselves now. Pilots at some airlines are
forbidden to land manually in bad weather. How is that somehow impossible for a flying car? In real production models, we'll
have multiple redundant mechanisms (parachutes, airbags, maybe even last-resort retro rockets), but it isn't impossible.
The rest about AI seems silly and myopic.

Take the fossil out. Spend a bit on equipment that is long-lived and self-repairing perhaps, but probably much less on energy.

It could be automated. Avoiding all advances in commercial agriculture would be a mistake, but cutting down pesticides is nice.

If we need resources, we'll find a way to get them. Sea water, sea floor sludge, rocks, whatever.

We just need to stop having too many children. Attrition happens fast enough for everything but
