In this special end-of-year episode, the tables are turned: I’m the guest, and I’m interviewed by Zac Gross — an Australian macroeconomist and long-time listener of the show.

We reflect on what I learned on the podcast in 2025 and what I changed my mind about. We also discuss the behind-the-scenes work of running the show, and my plans for 2026.
