Unfortunately, whether we are on the business as usual path (with double the expected natural resources believed to be available in the 1970s) or the comprehensive technology scenario (it is too early to tell), we are in for some interesting times between now and 2050. The original simulation of the Club of Rome is remarkably close to observed ground truth (https://www.clubofrome.org/wp-content/uploads/2022/05/Earth4...).

Collapse is one thing, but human extinction is another. We survived the ice age. Though we are unlikely to survive as long as rodents or crabs or sharks, the Copernican Principle says we have at least a few thousand years more to go as a species.
Survived two or three ice ages at least ... although the gene pool got pretty small at one point. On the plus side, all the easy fossil fuels won't be around any more. Life finds a way with DNA, so there might be more competition.
