Metatron,
There's no "you" appart from your neural conections. If someone could manage to reassemble each and all of your neural conections 100 years after you pass away, that person would feel the same sense of continued existence that you feel each morning when you wake up. It would be "you", in other words. Now, if someone put together two identical copies of your brain, then both persons will see themselves as "you". I think the problem arises when the concept of "you" is contemplated in a prospective way; in my opinion, it only makes sense in a retrospective way.
