As a civilization, we went from "grow what you eat" to "buy what you eat." Today, every member of our society specializes in something and collectively, we cover the overall needs of the society. This transformation took place a long time ago for our civilization and the same transformation is now taking place in technology.

My company, TrueVault (https://www.truevault.com) is definitely betting on this trend by specializing in being the data backend for healthcare apps, sites and devices.
