This feels like the invention of gunpowder, to me – but for the art of deception rather than war. Up to this point, a politician could say a different thing depending on who was in the room, and we would get an occasional peek at that: like HRC's public & private positions on Wall Street, or Romney's 47% comment. But now there can be 220 million different things to say in 220 million psychometrically-crafted rooms. That feels disruptive.
