When someone publicly admits they were wrong about #crypto and you manage to keep yourself from replying, "Told you so."

But I did. Back when #bitcoin was first a thing I told everyone it was a grift with insoluble computational issues.

And I was FAR from the only one. There were so many of us pointing out the problems.

But we were voices crying in the wilderness. In the end crypto proved even smart people can fool themselves into believing stupid things, if there is sufficient incentive.
