Once you say that you would die if someone else carries on, and that the other person doesn't have to be exactly you but can have for example a few minutes delta, then we get into the discussion of just what it is that makes your belief that they are "similar enough" that you can happily suicide. > "I'm not important, but I'm unique; nobody is exactly like me."; "I still want to live" I submit that if you were in the accidental clone scenario, you wouldn't be willing to die as you claim, but would instead feel "I still want to live" very strongly, and your belief that the clone is "exactly like you" would give way to "they just came out of a nano-assembler and they know it, they're only an approximation of me who knows how many things are subtly different inside, I deserve to live more strongly" or on the other side "I just stepped out of a nano-assembler, I'm new and fresh and they've been ageing for decades and they intended to die in that scanner, I deserve to live more strongly", or possibly "I'm willing to share everything I have and compromise, there's no need for any death here". > [ed: or continuity or linearity of experience, which I think are largely violated already when I fall asleep or lose memories] I'm not happy with the casual idea that continuity of experience is violated by sleep. If that were true, waking up somewhere "unexpected" would be impossible, instead it's very disorienting and scary and a trope of horror stories. We expect to wake up where we went to sleep, we expect any times of waking up in the night to be in the right places in the sleep timeline, and we expect to feel an amount of refreshed/relaxed/over-tired/too hot/aching/with a numb arm from lying on it/etc. depending on how long we slept for and how well we slept (which is something we are aware of and can report on), and we can experience waking up with answers or decisions to things we were thinking about the night before. Sleep is not 8 hours of non-event.
