I've attempted to use this iterative method with GPT4 to build an application, and things just get clumsier and more error-prone as the program grows in complexity. Eventually I get to the point where asking it to make revisions becomes a dice roll with respect to keeping the code behaving as expected or having it arbitrarily omit random portions of the application logic in the rewrite. It's certainly a great way to brainstorm or to quickly produce snippets of logic but it fails for anything beyond toy apps.
