The actual civilization, which is Bitcoiners, has in fact learned the lesson: let Keynesians push buttons on the money printer and you'll get hyperinflation. It's the government that forgot all economic principles.

The irrational exuberance is brought by fed policy. Bitcoin cycles are closely correlated with rising or falling interest rates and the 2020/2021 pump was strongly supported by the thousands of dollars ppl got for free during covid.

Hm. This doesn't look anything like a hard money standard. If I recall correctly, the lessons that civilization has learned is that fiat money always fails and hard money leads to prosperity.
