AI & Agents
Models, agents, and how AI products actually get built — separate from the infrastructure that runs them.

The Story You Tell About the Failure Is the Failure
Martin Seligman spent decades on a question that sounds too soft to matter and turns out to decide almost everything: not what happens to a person, but how they explain it to themselves an hour later. He found three dials. Is the cause permanent or passing. Is it everywhere or just here. Is it me…

The Best Filter Wins, Not the Biggest Toll Booth
There is a sushi counter in San Francisco called Sushi Zone. It seats maybe a dozen people, opens at five, closes at ten, and the line starts forming before the doors do. You would walk past it a hundred times on Market Street and never see it. Someone found it anyway — through a review…
