Then we had feedback from a listener, at least one listener, that They wish that kind of the podcast I go back to, it's more mathy roots.

His whole brand is practical finance, right? Making complicated decisions easier, which is also what this podcast is all about. But wow, what a conversation.

You have to cue it up, but man, I thought it was phenomenal. I saw James speak at a conference last year. He was actually speaking about Scott Sederberg's paper. He was a discussant. It was a great discussion of that paper.
