Complexity is the Ceiling: Software Design in the Age of AI Coding
AI coding tools have made writing code faster than ever, but the real bottleneck — understanding and safely modifying complex systems — remains entirely human. A 2026 study of over 300,000 AI-authored commits found that nearly 90% of introduced issues were structural code smells, illustrating how models optimize for working output rather than maintainable design. Clean, well-structured codebases amplify AI's benefits, while tangled ones cap them, making software design not less important in the AI era, but more consequential than ever.
