There's an awful lot of work being done, especially with blockchain. Great ideas with impressive teams. But it isn't showtime yet. It's heads down and working time.

A big reason behind the popularity of Citi bikes etc is the same: it delivers the convenience of having a bike, without the headache of having it stolen quarterly.
