Meet the robot humorists trying to build machines that make us laugh

Vinith Misra is one of the funnier people in tech. As a consultant for the hit HBO show Silicon Valley, he's best known for having crafted a mathematically complex dick joke. At IBM, where he works full-time on Watson, part of his job is to figure out how to give a robot a sense of humor. AI "is not about replacing humans, but interacting with them," Misra told me. "That's where humor is super valuable." We're going to be interacting with machines more and more, as robots and smart devices enter our homes, offices, cars, schools, hospitals and workplaces.
