Overlord is the best 5-episode anime, as I only acknowledge the existence of episodes 14-18, the rest is gorehound edge bait I can only recommend to people who are still flaming about the titan CGI. However, with what little I left on my hard drive, there was one thing still interesting:
The protagonist gets killed and then revived with bs. Now, revival via bs has the side effect of reducing your EXP and level, which means you lose skills.
While this is there because almost every damn isekai needs to have bs game mechanics in their setting (never The Hat Economy, though), I thought I'd make a reasonable explanation for that.
The idea is simple: since ISPs are rather stingy about giving me bandwidth, I decided to expand more on mind compression.
Initially, via specialized hardware, data structures, and lossless compression, and in the most recent step: lossy compression. Those ISP company executives weren't too happy about being lab rats, though.
Much like how you can still recognize an image of a rose with medium jpeg compression, you will still recognize your favorite athlete as the same person, even after they suffer a horrible injury and can only walk with crutches.
Of course, stripping muscle memory from the backup is only partial, giving resurrectees "steps" to climb back on.
However, I'm unsure if there is a point to that, or if muscle memory is too small to matter in compression ratios.
Do we know enough about the human brain to answer this question? If yes, would striping away some muscle memory significantly decrease the amount of data we would have to store?
