There are really good applications of blockchain, unfortunately most effort was focused on the dumbest ones. Take for instance identity management - hospital ticketing system, where the patient's records are linked directly and inextricably to the tickets, etc. You can request an appointment using a smart contract, and everything else will happen magically. Maybe someone worked on such systems, but they didn't get any airtime. I think eventually it will happen.
