This is a great article, but I disagree on one point. Blockchains aren't overhyped. Sure, people promote them for strange use cases sometimes. But I'm pretty confident that we'll look back on blockchains as underhyped. Blockchains will reshape entire industries, and some of the largest corporations on the planet will find themselves competing on a level playing field with a few kids in a garage.

Has disintermediation ever been overhyped? Currency disintermediated trusted community members who you knew would do you a favor in return. The printing press disintermediated the Catholic Church, one of the most powerful entities of its day. The internet disintermediated... lots of people. Blockchains disintermediate everyone else.
