Mental health as x-risk reduction.
Assumptions. People push hard for profit because they have inner demons, and hard profit seeking is something that is bad for AI safety. Then for things like nuclear war, perhaps such human conflicts would be significantly less likely to occur if people didn’t have inner demons.
Similar points could be made for happiness, with mental health being “move you from being in the red to being even” and happiness being “move you from being even to being in the green”.
