On occasion, albeit increasingly rarely, I find LLMs do something really unexpected that I certainly did not ask it to and would be way outside the scope of what any reasonable human would infer from my request. Is it my fault for running the LLM? Probably yes. But I think it's misleading to say "AI doesn't do anything until you ask it to".
But it never starts doing anything until someone or something prompts it. It doesn’t even exist until you ask it to do something.
It is autonomous in the sense it can continue to function without supervision after the operator has started it, in the same way countless programs on your computer are “autonomous”.
But it can never choose to begin doing something at any time of its own volition. It does not have “autonomy” like a human does.
The hallucinations from an LLM are still the result of the prompt even if they are totally senseless
That "probably" is the problem. If I do something I don't understand, and am not qualified to control, then I'm still at fault. If I start a fire, and loose control of it, it's definitely my fault. If I created a computer virus, ajd it worms half the Internet, it's definitely my fault.
