We’ll be back in September with new episodes of Revisionist History. In the meantime, I got to sit down with my good friend and host of Cautionary Tales, Tim Harford.

We discuss his recent trilogy about the epic race between two explorers to the South Pole and all the challenges they encounter along the way. We draw parallels between the 1920s explorers and Silicon Valley startups, and of course, who of the two explorers we’d prefer to have dinner with. Enjoy!
