I think the magic sauce in this project is the fact that they convert diffs in spec to diffs in code, which is likely more stable than just regenerating the whole thing.

The thing is, such exploration can be done on a whiteboard or a moodboard. Once it’s we settled on a process, we code it and let the computer take over.

I really believe the struggle is knowledge and communication of ideas, not the coding part (which is fairly easy IMO).
