I believe blockchain can be used for a lot more features in the future. This article is great in explain the essentials as we know it today. But as we see with many other technological innovations, it might be used for a lot more then what it is initially intended for. Just the smart contracts in general can add so much value to companies and certain deals. It just needs some time to get adapted by the public. Like the internet, it is very hard to explain what blockchain actualy is in a way that everyone understands. One day it will become a standard in the way of working, I am sure about that.
