This drives me absolutely crazy. My colleagues send me huge PRs to review (say 2000+ lines). I don't just paste comments from the LLM, I ask the LLM to review it, but I also review it myself. I only include ideas from the LLM if I think a) the LLM has gotten the issue right and b) it's worth having the developer take the time to address the issue. I always write the comment myself so I can add relevant context and put it in my own voice.

Then, after I've put in all this work, the developer just replies with a copy-paste of what the LLM thinks about my comment. I have no idea if the developer read or understood my point. I have no idea if he agrees or not. It doesn't just seem disrespectful to the effort I put into the review, it also leaves me in a difficult position as a tech lead because I have no idea if the person who is ultimately responsible for this code understands the code, my feedback on the code, or the changes that the LLM made to address my feedback. If you're responsible for a feature, I want to be able to feel like you're thinking critically about how that feature works. Right now, I just feel like you're blindly doing everything that I tell you. It also feels like I'm shouting into the void. We're colleagues, we should be able to have a conversation about technical subjects!
