Earlier quoted context omitted.
But politics impact me and my family and the world we live in. And some technologies do too! So it's natural and probably good to have thoughts and perspectives and positions on politics and technologies that impact me and my family and the world we live in (rather than be apathetic). Should we avoid polarization, and arguing by memes, absolutely! But like perpetual motion machine and eugenics and racism and trickle…
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.
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.
