First, I am not fond of the term RPOP, because it constrains the space of possible intelligences to optimizers. Humans are reasonably intelligent, yet we are not consistent optimizers. Neither do current domain AIs (they have bugs that often prevent them from performing optimization consistently and predictably).That aside, I don't see how your second premise follows from the first. Just because RPOP is a subset of AI and so would be a subject of such a theorem, it does not affect in any way the (non)validity of the EY's contention.
