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!
Do you consider your brain going in to sleep mode, providing you with filler content that you largely forget, and then waking you back again later to be the same as being vaporised in your original location?
… and recreated, at the atomic level somewhere else? Yes.
Full-body anaethesia is a better example. It isn’t sleep; your body is essentially dead, and machines are performing your normally autonomous functions for you.
They both involve a state of unconsciousness, but they are fundamentally different states. If you were under anaesthetic and, whilst under, they liquidised your brain and installed an exact copy of it in its place then you’d be cool with that?
No one would be the wiser and the original brain is gone, so no harm, no foul?
How do you know it doesn’t?
I think I would be OK with it. I’m not the same person when I wake up in the morning as when I went to sleep as it is; my brain is certainly different than it was last week, much less dozen years ago.
