I don't know if a lot of people will be really using Bitcoin ever. I don't see it happening soon. The questions I field from people who are already going off the beaten path more than the average person are still way in the area of quite dumb, and the attitudes are very often NOT the thirsting for knowledge it takes to really build your own infrastructure with it. Especially from the younger generations where attention span just isn't there. Perhaps we trend back better after society adapts to some of the insane parenting decisions and role of tech in child rearing gets addressed, but if nothing else it doesn't seem like it'll be changes I'll live to see.
And that's fine. Bitcoin works very well for small circular economies to maintain their purchasing power and grow without being leeched away from by the financial industrial complex. It can be used more broadly, but if it isn't, it hasn't failed.
