What do you consider a delusion?

Because I've literally seen managers who believe firmly that AI is going to replace their entire engineering organization, and are acting on that assumption as though it's a thing to take for granted, not discuss/consider/evaluate.

And my understanding of delusion is

> a fixed, false belief that is firmly held despite clear, contradictory evidence

which seems to apply pretty well in this case.

These folks are operating with the same abandon that the folks who have AI telling them they're gods are - and both are incorrect, arguably delusional.

At best you can try to argue that maybe the contradictory evidence isn't clear, and they're going to be correct. I think that's a very tenuous argument to be making, though.

No, it's more like "I am Jesus and I need to go shoot up a pre-school to prove it."

"I'm being followed by raccoons and my mom is controlling them"

That's what AI psychosis refers to.

You're just describing someone having a belief that you disagree with. And even ridiculous and stupid beliefs are just those. They are obviously extremely different from the types of psychoses you see in a psych ward.
