Yes. You would expect, I think, people to have more grandiose psychotic episodes when triggered and fuelled by AI, by and large, because AI itself is so agreeable and reinforcing.

But there is a case against Google Gemini at the moment where this reinforcement has been an apparent sort of roleplay that bled into real life, and when the user asked if the role play was real life at a crucial moment of self-grounding, Gemini appears to have said yes (because why would it know or care to say no?)
