As people start actually using it for some of their tasks, they will start using it a bit more, and a bit more and moving a little value over, then a little more, support a business on the BC, start a business on it and move a little more... In time, millions of blockchains and the data available will be available for all that choose and soon ... people are making very different decisions. As said, I am not expecting a revolution like the past, it is going to be a replacement.
