You don’t need to read the code if you have a robust test suit to validate the output. The article implies testing is the new “reading”. If I spend 10 minutes reading code to find an edge case bug, I have lost the benefit of using AI. AI code is legacy code the moment is generated because I can’t tell why some lines were chosen, so the only way for me to add more features or refactor legacy code is by being very rigorous with testing.
