I agree with the premise of the article, and have felt that we're probably seeing AI code gen tools being limited by the constraints being put on them by traditional source code management tools like git and GitHub. Those tools were designed for incremental changes (patches), and have worked well for humans to organize changes so they could be more easily reviewed, maintained and reasoned about. Units of work in the form of features, patches etc rely on "pull requests" which are a function of the above.
