““Personal identity” does not actually correspond to anything fundamental in the world, which is why some of the results of the anthropic trilemma actually feel weird to us, but it does still exist as a cognitive abstraction which our brains need in order to operate, and we can’t actually not believe in some kind of personal identity – at least, not for long.”
