I clarify:
Let’s say scientists can’t come up with solutions to global problems, AI gets out of control and turns almost everyone into paperclips during wars, and in the 2040s or 2050s, the surviving people (about a few tens of millions around the world or even less) gradually return to the level of intelligence of their distant ancestors?


For all y’all on here saying you have no survival skills: computers and electronics aren’t going to just go away, and the fact that you’re having this conversation on a federated internet forum means you know at least a little bit more about computers than your average bear. For any scenario where extinction is a possibility, being able to operate a computer and use it to communicate with other humans would be a huge asset, and the more of those people we have around the easier it’ll be to keep it going when things go to hell. Don’t sell yourself short.
Well, yes, there are actually still places with metals, those that are not yet known (which have not moved into AI and data centers), so computers can be revived over time, but only if there are unknown mines left in your country or region.
