Summary

Matt cites John Ousterhout's view, pointing out that AI is better at refactoring 'deep modules' with simple interfaces but rich functionality, while struggling with 'shallow modules' that have complex interfaces but single-purpose functionality.

Matt references John Ousterhout's *A Philosophy of Software Design*. Bad code = many shallow modules; Good code = few deep modules. What are shallow modules? They offer minimal functionality but have complex interfaces. When AI encounters this kind of code, it’s like wandering blindly through a maze. It has to understand a host of details for each module, and one small mistake can break everything. What are deep modules? They offer extensive functionality but have extremely simple interfaces. Complexity is hidden inside the module, exposing only simple, stable interfaces externally. AI thrives with this structure because it only needs to understand the interface to safely modify the implementation.
