I don't understand, can you please explain like I'm five
You'll die, and arbitrarily have NDEs, or experience a painful blackness, or whatever - and then your stream of perception, stripped of identity, will start popping up in Boltzmann brains (which are near-infinitely-but-not-infinitely unlikely quantum fluctuations that produce the exact physical duplicate of your brain), fetuses, &etc. in different Poincare repetitions of existence, to experience whatever hallucinatory and painful experiences they experience, all separate iterations that die out, until one of them, which will bear your stream of perception but not anything like what you identify as yourself, will be born and live a life that could, depending on the nature of recurrence, be either identical to your current iteration or quite radically different from it. There can and will be no continuity in this stream of perception until "you" are born again; each iteration in the sequence would appear as disjointed as the beads on a necklace.
The only interesting thing in this question is whether a recurrent existence is
identical to current existence in
all iterations (which will be massively unpleasant and numbing for me), or probabilistically different from current existence (which leaves everything in the air). It is almost-certainly the case that history would be self-identical
until you were born: Hitler will always have died April 30, 1945; Ronald Reagan will always have been elected November 1980; etc. But is what happens in
your life "locked in"? That's the question.
If there are different recurrences close enough that your stream of consciousness is produced in it - and never free will; free will is impossible - how closely related are
what has happened in this iteration to
what happens the next? Is there some probabilistic set that what happens in this iteration is arbitrarily similar to what happens in the next? I would
think the similarities are closest at the point of birth and diverge with time.
But really, you could just listen to this.
