You know those sci-fi teleporters like in Star Trek where you disappear from one location then instantaneously reappear in another location? Do you trust that they are safe to use?
To fully understand my question, you need to understand the safety concerns regarding teleporters as explained in this video: https://www.youtube.com/watch?v=nQHBAdShgYI

I wouldn’t, because the person that reappears aint me, its a fucking clone. Teleporters are murder machines. Star Trek is a silent massacre!
You are changing the question to “is a perfect replica of a person considered the same person or not?”. That is not the question.
What you experience by using a teleporter is you enter a room, and then you die. End of story. There being another replica of you somewhere does not change that you died. For an outsider they may argue whether or not you died, whether or not the replica is you, and so on. But from the perspective of someone who enters the teleportation room, it’s over. Dead.
