I don't see any reason why you should give up anticipation of future experiences. It's possible that in situations involving duplication and merging of minds you should accept that anticipation is an unreliable guide for decision-making, but that's not at all the same thing. (It's more like a religious person agreeing that if he gets seriously ill he should see a doctor rather than relying on his god to cure him -- which, in fact, religious people generally do.) At least for the present, the sort of switching and copying and merging and muddling of minds that would make our usual anticipation-based thinking fail badly doesn't happen to any appreciable extent.
