Reviewing code was never my favorite activity. It's slow, it's painstaking, it's cognitively taxing. It's pretty much a given that reading code is always slower, and less fun, than writing it.
So why would I ever do it? Because it's a collaborative process. I read your code, then ask questions and offer suggestions. We talk about them, we implement some things and not others. Together, we find our way and sculpt a patch we like. It's sociable, it's gratifying, and we get to share the satisfaction of co-creation. And it's based (ideally) on trust and respect: you did this work, and I would like to help you make it as good as it can be. Your success becomes my success.
If you're a person, that is.
If I have to review AI-generated code, or AI-generated writing for that matter, all of this flies out the window. I don't feel like a co-creator; I feel like I have to clean up a bag of dogshit left at my door. Anything good about the review process evaporate
