I also think it's possible this version of bitcoin falters and attempts to fork-restart it fail to recreate its immaculate conception (for a generation or two).

I think that only happens if bitcoin-the-idea rots, if it's culture can't hold the right idea in its shared mind long enough, but it's plausible. Bitcoin's culture is ripe atm, so is bitcoin-the-idea, and imho that makes bitcoin-the-system vulnerable.

Why is its culture ripe? We have some hypotheses.
