A car that actively kills people through negligently faulty design (Ford Pinto?) is one thing. That's bad, yes. I would not characterize ChatGPT's role in these tragedies that way. It appears to be, at most, an enabler... but I think if you and I are both being honest, we would need to read Gordon's entire chat history to make a real judgement here.
Do we blame the car for allowing us to drive to scenic overlooks that might also be frequent suicide locations?
Do we blame the car for being used as a murder weapon when a lunatic drives into a crowd of protestors he doesn't like?
(Do we blame Google for returning results that show a person how to tie a noose?)
