I have been listening to @EconTalker for two decades. It has become such a big part of my daily commute that it is hard to imagine driving to school on Monday morning without hearing Russ’ voice through my car speakers. Thus, it makes me incredibly happy to be the guest on this week’s episode, “The Great Fertility Collapse.” I felt like a kid who, 20 years later, gets to play for his favorite football team. The talk was fun, too, and we covered some of the topics I have often emphasized here on X: the facts about fertility collapse, what we know and what we do not know, and much more. As always, we didn’t have time to cover more. So, just remember my favorite line these days: fertility and artificial intelligence are the only two issues that matter right now. I can’t think about anything else.
