When you’re advanced enough to let go of concepts like having a soul, the idea of having your being destroyed and remade elsewhere becomes a lot let problematic. What’s the difference between being anesthetized and revived VS transported?
Shit, for all we know the universe just started five minutes ago and all of history is just a collective delusion. Just go with the flow and stop worrying about existential problems. One day you’ll die forever and that’s OK.
