This interview podcast features Stephen Dubner interviewing three guests at a live Freakonomics Radio show in San Francisco. The first guest, San Francisco Mayor London Breed, discusses her time in office, challenges faced, and future plans. Next, economist Koleman Strumpf shares his research on illicit activities like sports betting and cannabis sales, highlighting the challenges of obtaining data for such studies and the surprising prevalence of illegal cannabis shops in Los Angeles. Finally, economist Erik Brynjolfsson discusses human-centered AI, his proposed GDP-B metric (measuring consumer surplus), and the unique innovation culture of Silicon Valley. The podcast concludes with Dubner promoting an upcoming Los Angeles live show. A key takeaway is Strumpf's use of the Weedmaps app to gather data on legal and illegal cannabis shops in California, revealing significant discrepancies between the two.
