This reminds of some of the thought experiments in Sam Harris' book Waking Up. This particular one reminds me of the teleporter example which is in this excerpt: https://www.getflashnotes.com/waking-up-by-sam-harris/ https://www.getflashnotes.com/waking-up-by-sam-harris/ (just control-f for teleporter). Basically our reasoning about identity is poorly evolved for duplicates. The closest we can come to feeling comfortable with it is going to sleep and waking back up. I think mostly because we're just used to doing that (since otherwise going to sleep and waking back up is similar to dying and coming back slightly different). Was an interesting book overall - I'd recommend it.
