This is based on my keynote at RubyConf 2026. Video, references There’s a philosopher in Naples, Italy, way back in the 1700s who understood something important to software today. Giambattista Vico lived early in the Enlightenment, when mathematical and experimental thinking were all the rage. René Des Cartes and Francis Bacon were the hotness. People …
Verum Factum: we only really know what we made.
Dang, I know that feeling with software! And I miss it, now that AI is doing the coding.

TL;DR: Projects ask teams do what is asked of them; Products ask teams to invent their work. This requires a different way of seeing the world, and not everyone can do it yet.
