I suppose this kind of thing is fun to think about, but this kind of claim, which appears to be the main one, is metaphysical, not scientific, in that it appears to make no testable predictions, as far as I can see: > "Mathematical truth implies the existence of all computations. The existence of all computations implies the existence of all observers. The existence of all observers leads to a quantum mechanical reality populated with all possibilities and ruled by simple laws."
