What I don't get about the idea of an intelligence "explosion". In what direction should the intelligence explosion decide to go in and to what end? I mean you could say "in any direction", but that would seem kind of "stupid"? If you had infinite possibilities to choose from, which path would you explode towards? At some stage does "something" become so smart, that it doesn't make sense, even to itself. Imagine an ultra complex system changing at light speed, at what point does it trip itself up? I've worked with people like this, people who were ultra smart but couldn't slow down and actually achieve much. I love these thought experiments because personally, they make me realize that what we think about intelligence, consciousness and the self might be wrong. For me personally, they seem to have a Zen Koan type impact.
