@Purple So far I've only seen AI vomit from junior devs... Which got better over time, mostly because they learnt it's easier to review and fix it themselves before sending me a MR for review to which I reply, that they should fix the obvious stuff first and then get 30 comments from me in the following iterations anyways... 
Most seniors don't really use AI... Some even forget they have an AI subscription...
I'm one of the seniors that use it more often. But I'm using it more like a glorified search engine, getting inspiration for problem solutions (good way to find methods in libraries that I might have missed... if they exist and are not hallucinations), sometimes to get clues on cryptic compiler errors.
I don't usually accept generated code/changes but tend to do it myself after I understand the suggested solution. In my experience it's a lot faster than cleaning up up the generated code.
