There’s a mistake in today’s missive, as several alert readers have pointed out, bless you. The Frank Loesser song “No two people have ever been so in love” comes not from Guys and Dolls but from the movie Hans Christian Andersen, starring Danny Kaye. I know this. Guys and Dolls lives in my bones; I can still hear the scratchy LP of Hans Christian Andersen. Why the goof? Because AI, with his usual breezy insouciance, assured me otherwise, and I took Alistair at his word.

The fault is not Alistair’s, but mine. Even a genius like Alistair isn’t infallible. We all need supervision. As Reagan said to Gorbachev, back when Presidents spoke in sentences, “Doveryai, no proveryai: Trust, but verify.”
