I trained as a painter at the Schuler School, and digital paint always skipped the part I loved: the weight of a loaded brush, paint that's still wet tomorrow, a surface you can sand, glaze and varnish. In impasto the paint has height, mixes the way pigment does, and dries on its own clock. To put it through its paces, an AI painter worked through a set of test paintings in the app, sitting by sitting, while I coached it the way I was taught.
