James Heckman: Well, there's so many good challenges. I mean, there's a huge amount of work that needs to be done. One thing is exactly, there's a whole literature now of a kind of, I think, bad social science. It's called an industrial organization. People are saying, the famous economist Robert Solow wrote this essay years ago about the computer, and he'd say the productivity of the computer is everywhere but in the statistics. And so people are saying, wait, there's this productivity slowdown. And people just keep saying this over and over again. I was at a conference in Paris last month, two months ago now, where people were repeating this over and over. And the problem with that is that that's a model as a model for a technology of the 1920s and 30s. We don't know how to measure the productivity of things like AI, the internet, the ability to communicate, the fact that we can speak to each other this way. This was impossible 30 years ago. Now it's possible. It's easy. You take it for granted. You take wheels on bags is forgiven. But honestly, these kinds of things, I think, are very hard to measure. But the trouble is we use traditional measurement systems that don't catch up with what the new data are showing.首发2024-07-03 15:51·太空科学科普
