Some people find this offensive because they don't make very much, but for some people, it's a nice way to do something relatively mindless that brings in a little more money. My question is, how do we know they're labeling them correctly? Can't use the computer to check them, because that's the whole idea. So this is a problem. And I think most people don't maliciously mislabel them, but sometimes they get lazy and or they make mistakes because they're trying to do too many too fast.

Computer Scientist and author Melanie Mitchell of Portland State University and the Santa Fe Institute talks about her book Artificial Intelligence with EconTalk host Russ Roberts. Mitchell explains where we are today in the world of artificial intelligence (AI) and where we might be going. Despite the hype and excitement surrounding AI, Mitchell argues that much of what is called "learning" and "intelligence" when done by machines is not analogous to human capabilities. The capabilities of machines are highly limited to explicit, narrow tasks with little transfer to similar but different challenges. Along the way, Mitchell explains some of the techniques used in AI and how progress has been made in many areas.
