We're all going to live in NEOM / Mega City 1 / Asimov's "Caves of Steel" anyway. Or travel around a wasteland in a giant city that eats other cities. Or something.
You are probably not very wrong. Give it a couple hundred years and we probably will be the one’s living in the “habitat” and the bulk of the planet’s surface would be essentially wild. Population control will have to be faced sooner rather than later (I’d guess my Grandchildren will be the first generation to see inducement to either not reproduce or to reproduce at population stable levels).
Just as the world is very different today, than it was 200 years ago, so it will be unrecognisable to us if we could see it from here.
Look at the various forms of government and society that we have experimented with since 1824.
Christ, I can imagine trying to explain Dubai to my Great grandfather. Shit, if I could bring 10 year old me here, he’d be gobsmacked. Probably he’d be stumped at “yeah, the Soviet Union collapsed” and that would happen within 10 years of his time.
Edit: That does rather assume enough people survive what’s coming in the next 20-50 years…
