Regenerate Over Refactor: How AI Is Reshaping Software Architecture

AI has inverted the economics of software development: writing and changing code is now cheap, while running it at scale remains expensive. Traditional architecture patterns like Clean Architecture and SOLID principles were designed to minimize costly code changes, but they're increasingly unnecessary when code can be quickly regenerated rather than carefully maintained. The industry must shift from optimizing for human comprehension and changeability to optimizing for runtime efficiency and rapid evolution.
