Anyone who thinks there will be 10+ billion people on earth in 200 years is a doofus. I’d estimate between 200 to 500 million, with small but real possibility of extinction — say for instance if climate change precipitates resource wars which then go nuclear.
The world will look drastically, shockingly different in 200 years. That is just the reality.
I won’t be around to see it, and there will be far fewer people to do the seeing for that matter.
