Uh oh.
We're headed for a big crash in "just in time services that lose money". Remember Webvan and Kosmo. The business model of all these guys, including Uber, is "achieve monopoly, crank up prices". Probably not going to happen.
The experience of Austin, where Uber and Lyft pulled out over the driver fingerprinting issue, is instructive. Within a month, six competitors were up and running. The barriers to entry in this area are low. Even if someone does get market dominance, they can't raise prices much.
Uber is particularly vulnerable because their latest capital infusion of $1.5Bn is high-interest debt, not equity. That's an axe hanging over the head of a money-losing company.
