@Purple I haven't seen it at these extremes in AI yet (with seniors).
What I have seen is that someone pushed a huge upgrade out in record time, one that would normally require careful consideration and planning.
Turned out they instructed an LLM to do the upgrade and not much else, because I later spotted some pitfalls mentioned in the upgrade guide (and not a long one, either).
To me, LLMs are tools; you can use them, but they do not absolve you of your responsibility to at least try to do your due diligence as a programmer (which goes beyond writing code and shipping it).
