I'm OK with being downvoted for irrelevance but in case anyone doesn't get the reference:

A great deal was made of the change to Proof Of Stake, enough that it sort of became an end to itself, and the conversations about how exactly it would be safe or even a smart thing to do -- national energy output of country X notwithstanding -- got very hand-wavy.

And yet it came to pass.

The sci-fi reference linked here is about that, precisely. A big decision is made, the affected parties think they know all the implications, and yet -- well, see the movie.
