A veteran software engineer draws parallels between the Extreme Programming movement of the late 1990s and today's generative AI era, arguing that both represent 'rigor relocation' rather than loss of discipline. Just as XP replaced heavyweight processes with tighter feedback loops, and dynamic languages replaced static types with test-enforced correctness, AI-assisted development demands stricter specification of intent and ruthless evaluation of outputs. The core thesis: probabilistic code generation only works when deterministic constraints exist at the edges. Engineers who thrive will treat generation as a capability requiring more precision in specification, not less, and will build evaluation systems that fail loudly when code drifts from intent.
