To be honest, I tried to work with with GitHub Copilot to see if it could help junior devs focus in on the important parts of a PR and increase their efficiency and such, but... I've found it to be worse than useless at identifying where the real complexities and bug opportunities actually are.
When it does manage to identify the areas of a PR with the highest importance to review, other problematic parts of the PR will go effectively unreviewed, because the juniors are trusting that the AI tool was 100% correct in identifying the problematic spots and nothing else is concerning. This is partially a training issue, but these tools are being marketed as if you can trust them 100% and so new devs just... do.
In the worst cases I see, which happen a good 30% of the time at this point based on some rough napkin math, the AI directs junior engineers into time-wasting rabbit holes around things that are actually non-issues while actual issues with a PR go completely unnoticed. They spend ages writing defensive code and polyfills for things that the framework and its included polyfills already 100% cover. But if course, that code was usually AI generated too, and it's incomplete for the case they're trying to defend against anyway.
So IDK, I still think there's value in there somewhere, but extracting it has been an absolute nightmare for me.
