Sure, it’s “just about” right now, when it wasn’t that way not so long ago. It’s the “movement” and the direction of the movement.
Problem is it’s been “just about” since the mid-70s and really the last big step we took towards it was internet commerce which makes us buy a lot less in person. Prior to then it was debit cards. And this bitcoin idea is really nothing more than enhancing those, it’s either good for e-commerce or can be used like a debit card. If neither of those could get rid of cash the same with bitcoins ain’t gonna do it.
