I mostly get what you are saying, just hard to follow the details because I haven't studied PID in a rigorous way.

Anyway, it's interesting to wonder how many times the bell curve meme is right 🤣

One think about the simple solution first (satoshi's difficulty adjustment), then he learns that there are more sophisticated mechanisms, then after a deep dive he recognise that the first solution is good enough as the more sophisticated mechanisms give you some benefits but nothing essential.
