This is a really good video. The one thing that I don't hear much about the Block Chain is how many jobs will be lost. Just think of how many people that work at Real-Estate title companies as an example. With the blockchain, the job will be streamlined and many jobs lost. I think that it will defiantly help the medical industry. A simple example is shot records. This is something that should be available to a person, and if it's on paper then the risk is that it is lost, damaged or simply thrown out. The blockchain can help the medical industry that is bloated and to expensive. It could also stop double billing of services. The list of good and bad go on and on.
