It's becoming painfully clear that we have no idea how to run a society where machines do most of the thinking.
Maybe there will be a glut of smart people. Historically, that was the case until roughly WWII. Humans produced a certain fraction of smart people, but there were more smart people than jobs for them. Pikkety points out that through most of history, about 97-98% of the population was doing manual work. That started to change with the Industrial Revolution. Not until roughly WWII did an actual shortage of smart people develop. Hence the postwar boom in college education. Not until the 1990s did the nerds take over.
We think of a large group of smart people making society go as normal. Historically, it wasn't like that. The robust, the entitled, and the religious were in charge. Pikkety has a long analysis of this in his Capital and Ideology. Look who runs the Trump administration.
We're already at a smart people glut. In the US, only about half of college graduates find jobs that really need a college education. That's pre-AI. Now what?
