So, let’s say you die, but a super intelligence reconstructs your brain (using new atoms, but almost exactly to specification), but misplaces a couple of atoms. Is that ‘you’?
If it is, let’s say the computer then realises what it did wrong and reconstructs your brain again (leaving its first prototype intact), this time exactly. Which one is ‘you’?
Let’s say the second one is ‘you’, and the first one isn’t. What happens when the computer reconstructs yet another exact copy of your brain?
If the computer told you it was going to torture the slightly-wrong copy of you (the one with a few atoms missing), would that scare you?
What if it was going to torture the exact copy of you, but only one of the exact copies? There’s a version of you not being tortured, what’s to say that won’t be the real ‘you’?
Wouldn’t there, then, be some copies of me not being tortured and one that is being tortured?
If I copied your brain right now, but left you alive, and tortured the copy, you would not feel any pain (I assume). I could even torture it secretly and you would be none the wiser.
So go back to the scenario—you’re killed, there are some exact copies made of your brain and some inexact copies. It has been shown that it is possible to torture an exact copy of your brain while not torturing ‘you’, so surely you could torture one or all of these reconstructed brains and you would have no reason to fear?

Well.. Let’s say I make a copy of you at time t. I can also make them forget which one is which. Then, at time t + 1, I will tickle the copy a lot. After that, I go back in time to t − 1, tell you of my intentions and ask you if you expect to get tickled. What do you reply?
Does it make any sense to you to say that you expect to experience both being and not being tickled?

Maybe; it would probably think so, at least if it wasn’t told otherwise.
Both would probably think so.
All three might think so.
I find that a bit scary.
