The half of software that didn't get cheaper

Short summary

AI made code generation cheap, but code review—now the critical bottleneck—got significantly harder, not easier. AI-generated code is hard to review because it lacks intent and hides bugs through deceptive readability, yet tooling has focused on generation speed. The skill that now determines shipping correctness is systematic code judgment, and the ecosystem has built almost nothing to train it.

• •Code generation is cheap and fast; code review is now the bottleneck
• •AI-generated code lacks reasoning intent and masks bugs through readability
• •The tooling ecosystem optimizes for generation but neglects code review training

Generated with AI, which can make mistakes.
