I simply don't now if Block Chain is going to be the next internet. I will explain why. Internet is consisting of so much more than block chain alone. And block chain simply isn't the solution to everything. I think Block chain is absolutely making things on the internet more transparant. But you simply don't want everything to completely transparant. I can think of a thousand things I want to keep for myself.
So, blockchain will be a succes. But mainly in industries where transactions are a huge part of daily business. But it isn't internet. It's just one aspect of it.
