Personal identity is nothing but a convenient mental construct, imo. You're not the same matter you were at birth, nor can you make a good argument as to why you shouldn't be considered a direct physical continuation of your mother. It's practical to think of one as having a unique self that's distinct from its environment, but that doesn't reflect some deeper truth, it's just a framework for reasoning about the behavior of some arbitrary subset of the ridiculously complex system that is human society embedded in the more ridiculously complex system that is life embedded in the more ridiculously complex system that is the universe. Don't expect naive conceptions of self to survive that far into a future in which things like "brain uploading" becomes possible.
