Just thought I’d mention that if one wants to consider parfit’s thought experiment (the brain scanner that non-destructively copies you) and the underlying quantum mechanical nature of reality, you have to remember the no-cloning theorem.
Thus if you consider yourself to be a specific quantum state, parfit’s machine cannot possibly exist. Of course there are subtleties here, but I just though I’d throw that in for people to consider.
