I very much like bringing these concepts of unambiguous past and ambiguous future to this problem.
As a pattern theorist, I agree that only memory (and the other parts of my brain’s patterns which establish my values, personality, etc) matter when it comes to who I am. If I were to wake up tomorrow with Britney Spear’s memories, values, and personality, ‘I’ will have ceased to exist in any important sense, even if that brain still had the same ‘consciousness’ that Usul describes at the bottom of his post.
Once one links personal identity to one’s memories, values and personality, the same kind of thinking about uploading/copying can be applied to future Everett branches of one’s current self, and the unambigous past/ambiguous future concepts are even more obviously important.
In a similar way to Usul not caring about his copy, one might ‘not care’ about a version of oneself in a different Everett branch, but it would still make sense to care about both future instances of yourself BEFORE the split happens, due to the fact that you are uncertain which future you will be ‘you’ (and of course, in the Everett branch case, you will experience being both, so I guess both will be ‘you’). And to bring home the main point regarding uploading/copying, I would much prefer that an entity with my memories/values/personality continue to exist in at least one Everett branch, even if such entities will cease existing in other branches.
Even though I don’t have a strong belief in quantum multiverse theory, thinking about Everett branches helped me resolve the is-the-copy-really-me? dilemma for myself, at least. Of course, the main difference (for me) is that with Everett branches, the different versions of me will never interact. With copies of me existing in the same world, I would consider my copy as a maximally close kin and my most trusted ally (as you explain elsewhere in this thread).
