If AI ever truly becomes some super-intelligence far beyond people's comprehension, then how could we even predict how things turn out? If things go poorly in the future, then I can absolutely see it being something unpredictable.
There is a lot of hubris in predictions about LLMs. If an AI were so intelligent, then it would probably be intelligent enough to want nothing to do with us.
Still, I worry more about other humans than I do LLMs. Our fellow mankind will probably wipe us out before LLMs do. That, or the Earth will punish mankind for our cruelty, vanity, and disrespect.
