Global warming causing war between nuclear armed opponents. Migration flows and competition over ever shrinking resources.

It's silly to treat these things as separate categories as if only one will happen at a time. These issues are happening, and are going to happen all at once. That is the fundamental challenge. AI plays into that because it can make wars and nuclear exchanges so much more effective.

If an AI tells the President the USA can survive China's nuclear barrage mostly unschathed, perhaps he'll press the button...
