So did I understand correctly, believing in big world immortality doesn't cause you an existential crisis, but not believing in it does?
Yes - I mean existential crisis in the sense of dread and terror from letting my mind dwell on my eventual death, convincing myself I'm immortal is a decisive solution to that insofar as I can actually convince myself. I don't mind existence being meaningless, it is that either way, I care much more about whether it ends.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
