    If you make a perfectly exact replica of yourself do you suddenly perceive the universe from two perspectives?

      Presumably not without some means of information transfer, but that doesn’t mean that a replica isn’t you, because it could also mean that there are now two of you, both of which have an equally valid claim to the original identity, but which immediately diverge into identities distinct from eachother by virtue of having slightly different experiences after the split.

        That doesn’t answer the question. It’s obvious that the clone of you isn’t you, it’s literally just a copy. Unless there is some magic technology that keeps your brain alive and moves it.

        You are most likely vaporized. Although, faster-than-light travel literally breaks causation, and that’s possible in the Star Trek universe. I think that’s a bigger issue than transporters.

          That depends on what “you” are. If you are just your brain or nervous system, as in the specific atoms and such that make up that brain, then sure, obviously those atoms can’t be in two places at once, so you are wherever they are. On the other hand, if you are the structure of those atoms and particles, the way they are arranged, the patterns of movement they form as they go about their work, the information they contain by all this; then it stands to reason that a sufficiently perfect copy is the same as you, because if whatever makes you “you” is part that structure, whatever makes it “your” consciousness instead of someone else’s, and the copy has exactly the same structure, then the copy must also contain whatever that part is that makes it “you” and not someone else, and therefore has to be you as well.

          This isn’t a settled question, so one sort of has to decide what answer one thinks is more likely, I personally think the second.

          Consider a hypothetical for a moment. Suppose there are two people, I’ll call them Bob and Bill for the purposes of distinguishing them. Suppose they get captured by some sort of mad scientist, who runs an experiment on them both. They wipe the brains of both people in such a way as to not completely kill them, but such as to remove every trace of their memories, personality, etc, essentially rendering them braindead, but without the physical damage that usually entails. Then, they painstakingly re-create those same neural pathways, same memories, personality, etc, but they recreate Bob’s persona in what is originally Bill’s body, and likewise, recreate Bill’s memory and personality in Bob’s. Which of these two people is now Bob (or if one thinks neither really are and that Bob is just dead, who at least has the better claim)? The one that has the physical brain, nervous system etc of the original Bob, but remembers and thinks exactly like Bill? Or the one that acts like Bob, and remembers being Bob, and probably thinks he is Bob and would insist on his being such, but does not have the same material in his brain as the original? If one of Bob’s friends raids the lab trying to rescue him, which should he take back home?

            That’s all a semantic argument. It seems obvious that if your brain is “wiped” as you put it, you are gone. Cloning or copying you doesn’t solve that, in the same way that you are not the same as your twin.

            Your philosophical argument of “it’s complicated” is just muddying the water. When twins are born they are two different people. No one ever says “I’m so confused, there are two of the same people!”
