As far as I can tell the problem is a series of disconnected motives. The VC's have money to burn and want to become the next level of rich, which requires striking gold, often in fields they have no real conception of. The "disruptors" also want to strike it rich, but they can do that just by getting the VC capital and chalking the devastating losses they wont' personally suffer up to "valuable experience". Then of course success isn't necessarily contingent on providing a reasonable service at a sustainable price... see: Uber.
