Yes.
To everyone who’s answered that it doesn’t matter if you stops existing, since you-prime lives on with the same conciousness:
What about a scenario where you-prime comes out the other side of the teleporter and goes about its business, but instead of being vaporized, you is made into a slave, subjected to torture, etc. You-prime’s experience is exactly the same no matter what happens to you. So is the enslavement scenario equivalent to the vaporization scenario?
