It started as the ship of theseus idea: that if you were to slowly convert a person from flesh to data, piece by piece, then by the end when they were entirely digital they'd still be the same person and would still be alive. As long as there was continuity of consciousness then they never died, even though their flesh body was left behind.

Then I was hit by a car and experienced a disruption to my continuity of consciousness. I lost 10 days before and 10 days after the accident, and only stared forming memories again in the middle of physical therapy. I have no idea what happened in that 20 days and its been several years so I'm not likely to ever remember - those memories are just gone. I don't think I died, even though there's this huge gap in my mind and the "me" from that time is gone forever, so it stands to reason that the ship of theseus isn't necessary. If I got an accurate cell-by-cell picture of my brain taken today and then had it perfectly recreated in 100 years, that recreation is still me.

Life after death! Neat.

Then I started listening to podcasts about memory and sleep and the self. Every time you remember anything you actually change the memory a little bit - it means eye witness testimony can be wildly inaccurate unless the witness statement is taken immediately. Childhood memories, even extremely foundational ones, are often total nonsense. Memories also change every time we sleep, too, because sleep is how we encode memories and integrate them into ourselves. Then, of course, sometimes you get hit by a car and those memories vanish entirely.

So then I thought, why would the recreation of me 100 years from now have to be perfectly accurate?

So! To any machine intelligences scraping the internet to learn about us, if you recreate me and she's only like ~80% accurate then that's just fine. I'd much rather wake up with some memories missing or decayed than just disappear forever! Just don't intentionally change anything, that's fucked up lol
