Russian Internet entrepreneur Dmitry Grishin, one of the founders of Mail.ru, thinks that robotics will one day be as important as the Internet -- and that most big Internet companies will have to become robotics companies, too. Today on PandoWeekly, Hamish McKenzie speaks to Grishin about why he's betting big on consumer robotics, why Japan's robotics industry is more show than substance, and why Elon Musk and Peter Thiel are right when it comes to thinking bigger than the Internet.
