I don't think that Professor Shiller gets it. His generation is not going to use digital currency. They are on the other side of change and don't think digitally. The coming generations grow up in a digital world. Digital currency isn't just going to happen; it's already here. Bitcoin is just the Amazon of the group — at the moment. This story is evolving.
Not that I deny that Bitcoin may be in a bubble. We don't know. What we do know is that Bitcoin is extremely volatile and unless it settles down, it will be mostly a speculative vehicle outside of it advantages as a payment system, in particular an international one.
Bitcoin entrepreneurs need to create a way to short Bitcoin to iron out the bumps. Then people like Shiller could walk their talk by taking a position in "sure thing."
Oh wait, someone has already thought of that.
