It was because of his expertise in just the evolution of the financial system, generally. For example, Mark and I had a recent discussion about the interplay between stablecoins and the interest rate paid on treasury bonds. It's like a kind of arcane but, maybe in certain ways, an important kind of macroeconomic issue. I find Mark to be a really insightful thinker on those kinds of central bank macroeconomic topics. We don't engage and haven't engaged on the more purely political matters.
