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.
I wasn’t even thinking about the Boltzmann brain scenario, I was just considering the chance that literally everything could reform like this as we take time out to infinity, all slightly different permutations too
