I came across this today and thought you all might enjoy it. This is a 30 minute talk by Jeremy Rifkin about the rise of the third industrial revolution. He identifies an an economic/industrial revolution as containing simultaneous breakthroughs in three areas: communication, energy, and transportation. By this measure the first was telegraph + steam + rail, the second was telephone+oil+combustion engine/car and the the third is all driven in one way or another by IoT (communication, green tech,autonomous vehicles). All of which is both enabling the sharing economy, prosumers (combined consumers and producers) and an a near zero marginal cost society.
