In any case, I think we can all agree that one shouldn't compare cryptocurrency to a perpetual motion machine. It's a real technology, with real utility for the people whose problems it solves.
Sure, and it's also different than racism, which is a prejudice toward other human beings based on criteria they have no control over.
The list was heterogeneous analogies to illustrate a point, not equivalences. And that point was: there are concepts which are not obscure and no longer new and people have had some experience with, and its ok to have a negative reaction about them until and unless some pretty darn novel new evidence or argument comes up (yet there exists a set of people who still buy into it and don't understand the negativity). Like, I have a friend who's into crypto currency and I know a guy who's into racism and I have an uncle who's working on perpetual working machine... and they'll all get a "negative gutural reaction" from me.
Okay, but the fundamental difference is that cryptocurrency works as intended and provides value for an entire economy of people even during this experimental phase where we are still working things out.
