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.
Spock had a soul and that is canon. His soul (or whatever it was that made Spock more than the sum of his sexy, sexy green parts) was so important to his friends they quit their jobs, stole their own ship, crashed her, stole another one then got Spock’s soul out of valet parking just in time by THISMUCHSECONDS before it (or he) got lost forever.
TLDR: souls are a thing for Vulcans, why not everybody else? Vulcans haven’t advanced beyond the concept at all.
