>But it is clear that AI can contribute to psychosis in people who were otherwise in control of their lives in stressful circumstances.

It is only clear in the sense that 'can contribute' can be used as a catch all. I'd like at least evidence of it being a significantly greater influence than the myrad of stimulus that people are exposed to every day.

>It's not difficult to see how an infinite confirmation machine that never has any instinct to stop reinforcing your thoughts or impulses might cause and exacerbate a psychotic episode in people who have quite ordinarily heavily stressful lives.

True, but no such machine exists. If you think otherwise, feel free to prove that it does. That requires a higher standard than opinion.
