Very good point. And I loved the blockchain horse graphic! Just thinking off the top of my head here, but I wonder if part of the reason has to do with the mentality of the tech world? In Silicon Valley, for example, there seems to be a real push to get a product to market as fast as possible. Products are released in "beta," a little bit half-baked. Companies are encouraged to create a Minimum Viable Product (MVP) rather than a fully-featured, fully-tested product. That might work with an app... but not with a blockchain project!
