Well the person being teleported would cease to exist. If life is deterministic then there is no consciousness, just a predetermined path. So my argument is basically that you don’t exist anyways, and by that extension teleportation is not a problem, because the copy is not alive either.
Oh, I am very aware of it being like death. My point is that we were never alive at all. We have no consciousness because of determinism, we follow a path that cannot be changed. That’s why teleportation is not a problem from a deterministic atheist standpoint.
However I do fully acknowledge that I can not live like that. I live as if I have free will, because that is the easiest and most comfortable way to live. Beside nature / nurture arguments of course, I don’t dismiss those.
