The New Code - Specifications as the Fundamental Unit of AI-Era Programming

Explore how specifications are becoming the fundamental unit of programming in this 22-minute conference talk from the AI Engineer World's Fair. Learn why spec-writing has emerged as the new superpower for developers as AI transforms software development, shifting focus from code writing to precise communication of intent. Discover how rigorous, versioned specifications serve as the source of truth that compiles to documentation, evaluations, model behaviors, and potentially code itself. Examine real-world examples including OpenAI's Model Spec and draw parallels to how the US Constitution functions as a versioned specification with judicial review. Gain insights from production experience on how executable specifications can align both human teams and machine intelligence, and consider open questions about the future of developer tooling in an era where communication becomes the most critical engineering artifact.
