These catastrophes aren’t going to happen in time doomerbro. Tech bros hunting for food in 2045? Not a chance. Worst case scenario, where everything you say happens, rich people will simply move to habitable areas and continue right along while the rest of us get fucked. As always the rich will survive and they’ll employ the best minds to continue striving for LEV, AGI, ASI, and the rest. You think wealthy elites don’t have alternatives in motion for every single thing you’re suggesting?

Your best bet is a Covid variant that kills 80 percent of the people it infects. Even then people will adapt, survive, and keep innovating.

Long term I’m not downplaying what you’re saying. I agree with a lot of it. I just don’t think it’s going to destroy our world before these advancements get here. I also am not sure why these tools wouldn’t solve a lot of the problems you bring up.
