Is Star Trek teleportation OK?
As I see it, teleporting works by creating an entity ('B') with the memories of entity A at some other point in space. From the POV of B, it appears as if he or she has simply and conveniently changed location, but what about A? A is completrly destroyed. I suppose that if you are teleported 'You' are 'A'... so is B also you, or a stranger with your memories?
If A has any awareness during the process and the teleport distance was just across the room say, then A could even be aware of B taking shape - would they think B was them as they felt themselves fading away?
It's a given that teleporting is not technologically feasible, but even if it was, would consideration of "identity" mean it could/should not be used?
