Not defending AI here, but this sounds like people who are sick with some kind of illness are going down a rabbit hole with AI, and are unable to differentiate between imaginary and reality.

We had a family friend who worked with jewelry his whole life. He got some kind of poisoning from something he worked with. Lead? Mercury? I cannot recall

Anyways he started believing he was some kind of messenger from God. Nobody figured out it was poisoning for years. He was such a nice guy. He just wanted to help people. Once they figured it out, he was treated and went back to his normal self.
