Can AI turn a sketch into working code?
Yes. Several tools do it today, and it works. A multimodal model can read boxes, arrows and labels from a drawing and produce running code from them. The differences between tools are what the sketch becomes afterwards: in most, the drawing is a one-shot prompt that is discarded once code exists; in a few, it becomes a persistent model of the system that the code is checked against as it keeps changing.
