1. It's turning the Engineering work into the worst form of QA. It's that quote about how I want AI to do my laundry and fold my clothes so I have time to practice art. In this scenario the LLM is doing all the art and all that's left is the doing laundry and folding it. No doubt at a severely reduced salary for all involved.
2. Where exactly is the skill to know good code from bad code supposed to come from? I hear this take a lot I don't know any serious engineer that can honestly say that they can recognize good code from bad code without spending time actually writing code. It's makes the people asking for this look like that meme comic about the dog demanding you play fetch but not take the ball away. "No code! Only review!" You don't get one without the other.
