Yuval Noah Harari imagines a world where the human race has conquered death and become amortal. What are the implications for human society then? Do we stop procreating?

There is a movie based on this idea where the last person on earth dies of natural death. The movie was a European film called Mr. Nobody. Unfortunately, the movie is more about alternative timelines than the implications of amortality.

I wonder why Harari stopped at Amortality and not Immortality. If it’s imaginable that humans can develop technology to forever prolong life so long as the person doesn’t get run over by a bus, why can’t technology transfer our mind and memories? Isn't our existence simply a collection of memories and experiences?

However, scientist frequently purport that our memories are flawed and that we change or forget many details. I wonder about the accuracy or validity of their tests. How do you claim someone's memory is flawed when memories are personal interpretations of experiences? Experiences must be so difficult to put to words because of the unimaginable amount of information captured in an experience. Maybe our memories aren't flawed but what and how we choose to "describe" that memory is simply incomplete. I will need to read up on some of these studies in more detail.

I recently heard on NPR about studies at MIT that have shown Gamma Light Treatment efficacy in reducing memory loss on mice. Additionally, there was research attempting to prove that we don't actually lose memory. We simply lose place of memory but our memories can be refound if the area of the brain where it's stored is reactivated. This reminds me of an episode in Black Mirror about having perfect memory and the implications of it. It could be a blessing and a curse in that there may be memories we wish we could forget.

Would you really want to wipe certain memories if you could?

I don't think I would. Going back to my question above, I feel like our memories and experiences, no matter how good or bad, make up who we are and define our existence. To destroy that would be to destroy your own existence. However, the existential question I've been pondering is whether you really existed if your memories or memories of you cease to be passed on, or cease to exist.
