The final WTF episode was recorded with President Barack Obama. And it is exactly the type of interview you’re hoping to hear. The perfect period endpoint on what is a 16-year-long run of one of the greatest podcasters to do it.

What surprised me about the interview is the sincere friendship between the two men. I won’t spoil anything here other than to say it’s a warm, and times funny, chat between two guys who spend a lot of time thinking deeply on the important things in life. And working to find the achievable pragmatic path in life.
