Episode notes

Unsupervised learning still has the same sort of, we don't quite know what it's doing. We're just feeding it these answers. The things that they're doing are much more complex and we're in this weird situation where we can get them to do all sorts of very cool things, but our ability to understand why they're doing the cool things lags far behind.

They operate according to rules we can never fully understand. They can be unreliable, uncontrollable, and misaligned with human values. They're fast becoming as intelligent as humans--and they're exclusively in the hands of profit-seeking tech companies. "They," of course, are the latest versions of AI, which herald, according to neuroscientist and writer Erik Hoel, a species-level threat to humanity. Listen as he tells EconTalk's Russ Roberts why we need to treat AI as an existential threat.
