This has been a big part of the job for anyone on a team for at least 20 years. I do agree that it’s the hardest and worst part of the job, and has now become the majority of the job for anyone who isn’t vibe coding. So, that sucks.
The largest problem these days is the volume of code developers are expected to review. The volume went up significantly.
By far the biggest problem 90% of developers have with AI is that they should be turning off comments, as it's clear that the training data they have is no good for developing a theory of mind for an engineer who has to read them.
I've turned them off and add them myself at review time and am quite happy.
This is the best and worst thing about LLM coding agents. They trust comments way too implicitly. And then the errors just keep compounding.
Or a temporary hack that becomes "load-bearing" because the agent doesn't figure out that it's supposed to be a temporary testing shim - instead it keeps building on it until it basically duplicates what it's mocking.
Anybody who has reviewed pull requests can tell you that sooner or later you approve a PR after many rounds of changes because it's finally "good enough".
Fighting with a robot to just do the damned thing is less fraught because they don't get offended by critiques but it takes more round trips to get them pointed in the direction you want.
