Nobel laureates sound the alarm over Artificial Superintelligence

There's no shortage of doomsday scenarios involving Artificial Intelligence. But the warnings boil down to this: AI is an existential threat to human life. Some have called the warnings alarmist. But this week, several Nobel laureates and big-name celebrities cautioned that the threat is real, particularly when it comes to what's known as Artificial Superintelligence. Max Tegmark is the head of The Future of Life Institute. He's also a professor doing AI research at MIT. He spoke to The World's Host Marco Werman about why experts - including him - are calling for urgent action.
