How do you know the net value add isn’t greater with the AI, even if it requires more code review comments (and angrier coworkers)?
What value is that person adding? I can fire up claude code/cursor/whatever myself and get the same result with less overhead. It's not a matter of "is AI valuable", it's a matter of "is this person adding value to the process". In the above case... no, none at all.
The MIT study just has a whole host of problems, but ultimately it boils down to: giving your engineers cursor and telling them to be 10x doesn't work. Beyond each individual engineer being skilled at using AI, you have to adjust your process for it. Code review is a perfect example; until you optimize the review process to reduce human friction, AI tools are going to be massively bottlenecked.
