The human cost -- and potential profit -- of AI

Oxford University researchers have estimated that 47 percent of U.S. jobs could be automated within the next two decades. With everything from Amazon Go's cashierless stores to automated customer service to robo-advisors and driverless cars, we are moving toward a world with more productivity and fewer jobs. As many have commented, this is very reminiscent of globalization and outsourcing. But, with outsourcing, we only did half the work -- we struck trade deals around the world and increased productivity and corporate profits, but forgot to help retrain the work force to land jobs in the new economy. The result was an entire population left behind, and populist reactions like Brexit and Trump.
