That's not an AI workflow. That's how any solid dev process should work regardless of tools.
Full circle. If one has to do the full process of decomp, one might as well just noodle the code and save on the power/compute bill. The human brain is pretty goddamn efficient compared to a rack full of server hardware and GPU's. Of course humans also come with a problem from a capitalist's point of view. Three really. You can't own them, they aren't trivial to reproduce, and they can say no. AI has no such limitations. Hence the catnip like quality of the space.
