In Bruno's person-duplication thought experiments, there is a distinction between 1p and 3p that makes sense in that context. But this does not carry over to QM, where there is no viewpoint that sees fully unitary quantum evolution. Bruno seeks to avoid this fact this by defining a first person-plural (1pp) point of view. But that is just another name for what is normally considered the third person perspective. Changing the name does not change the substance..... The randomness of QM is third person and objective.

Likewise, the first person experiences of your friend follow one path of the quantum branching -- we do not experience all branches of the MWI simultaneously. Your arguments against the conclusion of Goedel and Turing have no merit. Bruce -- You received this message because you are subscribed to the Google Groups "Everything List" group.
