My pet theory is that billionaire weirdness and AI psychosis have the same root cause: talk too much to sychophants and the human mind starts to go off the rails.

Without a reality check, the natural feedback loop that tells us we're wrong sometimes, the human mind starts to diverge into madness.

Upon reflection, I'd add some amount of spoiled child syndrome or affluenza[1]. Both of those are environments where children and adolescents are removed from consequences due to someone not telling them they're wrong or removing natural painful feedback mechanisms of reality.
