>>12620871Our brains build composite patterns to store memories and attempt to purge old ones. Eventually those composite memory patterns are going to overwhelm our brains such that we forget things until we can only remember the blank staring void or we run out of space for our brains compression algorithm to fill and simply are unable to aggregate new memories. Some combination of the two is likely to occur. Combine this with the known phenomena of the perception of time increasing in speed as we age due to relative time experienced even if we are somehow able to retain these memories with any fidelity after 10k years our time perception will absolutely fuck us over if we tried to interact with normal people again.
That's not even mentioning that humans need feedback or we start freaking out. It's why solitary confinement does so much brain damage to people.
