I think we would. Suppose you put coffee in a cup. One second after you drink it. Now, both with the comp hyp., or with just the quantum hypothesis, you know there are quantum or comp continuations in which the coffee will be transformed into tea (or white rabbits ...). Suppose God prunes all the branches where the coffee does not change, then, during that second, the probability of drinking coffee, relatively to tour experience of having put coffee in the cup, will be zero. I guess you will noticed the difference. Recall the seventh step of the UDA (in the SANE version of UDA with 8 steps). You drop a pen, and you evaluate the probability that the pen hits the ground (if that is english). By the comp first person indetermincacy, the comp-exact first plural calculus, in principle, consists in considering *all* computations in UD* (i.e. generated by the UD in Platonia where we are supposed to be infinitely patient) going through your "actual state" (i.e. the one when you will just bring the cup to your mouth), and to see what is going on (from some third person pov) in each of the consistent computational continuations. If some "comp Goddess" was able to prune, the way she wants, the computation or their continuations she could change arbitrarily your local physical laws, and unless she decides to revised your memory (and thus your actual states) you would notice. All right? This should answer your questions. About your question "could a recording be conscious?" Well, let me quote you: > But WHY can't a recording be conscious?

True, I am surprised by my experiences > and believe I could have acted differently had I wanted to, but that > might all be part of the script to which I am not privy, so that things > could only have been different if the recording had been different. I think I mainly agree with you, but I have some reason to discard expression like "a recording can be conscious". If it is a recording of a (genuine) *computation* (unlike just a program), you can *associate* consciousness to .... not really to the recording, but to the "person" having that piece of computation recorded. That is, I think only "person" can think. I don't believe a brain can think, nor any piece of local "comp-matter". Only persons think, and only first persons are aware of thinking. Giving your other posts, I think this could just be a terminological nuance, but it helps to separate persons and their many relative third person (or first plural) incarnations/implementations.
