This just happened to me this week.

I work on the platform everyone builds on top of. A change here can subtlety break any feature, no matter how distant.

AI just can't cope with this yet. So my team has been told that we are too slow.

Meanwhile, earlier this week we halted a roll out because if a bug introduced by AI, as it worked around a privacy feature by just allow listing the behavior it wanted, instead of changing the code to address to policy. It wasn't caught in review because the file that was changed didn't require my teams review (because we ship more slowly, they removed us as code owners for many files recently).

As it was foretold since the beginning, IA use is breaking security wantonly.
