A lot of the new technologies only provide ideological benefits for most people. I don't think the concept of decentralization is in itself enough to cause mass adoption.
I love that there are strong proponents of this tech,though. It's nice to have alternatives in case centralized authorities go off the deep end.
It’s not a case of if, it’s when. These various technologies will eventually find there way into the mainstream for the exact same reason that the Internet did, because ultimately it has a democratising effect that the vast majority crave, even if they don’t think it’s possible yet.
