It is arguable, and quite rationally so, that a copy of you cannot contain 'your' consciousness, especially if you already exist when the copy is created and thus already possess 'your' consciousness. And to me this is the whole issue with Star Trek type transporters, immortality via uploading to a computer, etc, etc...or with the idea of cloning copies such as in the Altered Carbon series or in the game Eve Online.
I think all those alleged future technologies are defying some pretty basic laws of physics. Why would a copy of me be the actual me...any more than the next door neighbour's identical car ( that rolled off the production line at the same time ) could be my car.
Of course, there is a sort of counter-argument in the form of a 'Ship of Theseus' bit by bit replacement, but I think with enough analysis even that fails. We won't be quantum entangling our consciousness to clones on Beta Reticuli....not only not any time soon...but ever.
Well, with that attitude, no clone is going to want to be entangling with your consciousness anyway!
