L2 founder and New York University professor Scott Galloway talks with Recode's Kara Swisher about how the biggest companies in tech are disrupting retail, jobs, advertising and more. Galloway says the U.S. is incredibly "over-stored" and predicts that Amazon is well positioned to quadruple what its Prime customers spend. He also explains why most brands should worry about their future stability, and what a handful — including Apple and Disney — have done right to defend themselves. Later in the show, Galloway grades how Google, Facebook, Netflix and more are doing and makes the case for executive changes at Uber and Snapchat.
