The hype around the blockchain reminds me of the hype around XML around 2000. People were blown away by the potential... but no one could quite demonstrate it with a product. Now the blockchain can point to cryptocurrencies as a success story, and XML can kind of point to HTML, but it is a reminder that real change in tech happens when someone comes out with a product where the rubber meets the road. When everyone is talking potential potential potential, I am very skeptical.
