Tech moguls butt heads over the future of artificial intelligence

Facebook CEO Mark Zuckerberg criticized those comments during a Facebook Live session without using Musk's name. Robert Safian, editor of Fast Company magazine, joins "CBS This Morning" to discuss advantages and concerns of artificial intelligence.
