People obviously turning out LLM code uncritically should be investigated and depending on the findings made redundant. It's a good thing that it allows teams to filter out these people earlier. In my career I have found that a big predictor of the quality of code is the amount of thought put into it and the brains put behind it - procedures like code review can only catch so many things, and a senior's time is saved only when a junior has actually put their brain to work. If someone is shown to never put in thought in their work, they need to make way for people who actually do.
