Then, suppose AI does somehow think itself into effecting human annihilation, what happens when all the humans are dead? At the current state of things, all electricity production on the planet goes dark in maybe two weeks. Nuke plants irradiate significant parts of the earth, chip fabs are bricked, metal production is toast. In short the AI necessarily dies too.
The only way for this not to happen is AI controlled robots first gaining complete control of massive chunks of the economy. If AI is as useless as the article claims then that will effectively never happen. Thus, AI doom scenarios are always a murder suicide situation, and I’m not sure I believe anyone who says a superhumanly capable planner would pursue that plan. It even negates the “paperclip optimizer” as the AI’s demise obviously puts a hard upper limit on the number of paperclips produced.
