AI behavior on the other hand can cause under-informed users to do crazy things that no one would ever want. The form of the harm is less predictable, the magnitude isn't limited by anything except the user's ability and skepticism.
Imagine whatever US president you think is least competent talking to ChatGPT. If their conversation ventures into discussion of a Big Red Switch That Ends The World, it's going to eventually advise on all the reasons the button should be pushed, because that's exactly what would happen in the mountains of narrative material the LLM has been trained on.
Hopefully there is no end the world button and even the worst US president isn't going to push it because ChatGPT said it was a good idea. ... But you get the idea, and there absolutely are people leaving their families and doing all manner of crazy stuff because they accidentally prompted the AI into writing fiction starting them and the AI is advising them to live the life of a fictional character.
I think AI doomers have it all wrong, AI risk to the extent it exists isn't from any kind of super-intelligence, it's significantly from super-insanity. The AI doesn't need any kind of super-human persuasion, turns out vastly _sub_-human persuasion is more than enough for many.
Wealthy people abusing a new communications channel to influence the public isn't a new risk, it's a risk as old as time. It's not irrelevant, by any means, but we do have a long history of dealing with it.
