From where I’m sitting, it looks like death should not be the end in that case.
You can’t perceive the passage of time when you are dead, so you’re just going to experience dying and then immediate rebirth after the countless eons pass for that rare moment where entropy spontaneously reverses to form your mind again.
What is this “rebirth”? There’ll be many births, perhaps many similar to previous ones, but what makes “re”? Right now, everyday on earth (perhaps on other worlds) there are many births of people who are quite similar to you already, why do they constitute any less a rebirth than someone a thousand billion years from now?
My lot isn’t with “me” and me being eternal or me reborn. I’m part of the totality.
