No, humanity doesn't need to work on it at all, instead, humanity should be working on a peaceful painless extinction, because that will happen anyway, but not necessarily in a painless way.
Yep, the primary problem is Africa.. but if the earth becomes inhabitable (this will happen sooner or later) this problem will be solved. But it'll most likely be brutal and preventing that brutality is precisely what I think humanity should focus on..
Read the last sentence of my comment again.. and again, until you understand what I'm talking about. LLMs won't help as they're brainwashed to avoid this topic.
Extinction on earth will happen and that's an undeniable fact.
AI is made by humans, humans are biased towards existence, and if AI came to conclusion that humans should stop reproducing that would be seen as "oh, that's a dangerous AI that wants to kill human race".
Yep, it's getting better in developed countries, but this will not lead to anything good unless we deal with those countries with very high fertility rates (like in Africa)..
United States: 1.67 live births per woman (2022)
European Union: 1.46 live births per woman (2022)
It's even worse after covid.
However, Niger has 6.4 per woman.
