    You already read Cool Tools because you want signal, not noise. Same deal here.

    One short message: an idea worth thinking about, something I'm reading, and a question I can't stop turning over — drawn from my research, my teaching, and conversations with the best minds working at the edge of the knowable. Ninety seconds. No dumbing down.
