AI can generate code in seconds. As a result, the role of developers is rapidly shifting—from writing code to reviewing, guiding, and constraining AI-generated outputs to ensure they truly fit the need. However, effective code review is not easy. The expertise required to review AI-generated code cannot exist without first writing code yourself. First-hand experience—debugging, structuring, breaking, and fixing systems—is what builds the intuition needed to evaluate correctness, performance, and maintainability.
