I disagree.
From ICs that I lead, I expect that they learn fast. On the other hand, LLMs are basically incapable of improving.
Another issue that I can see is that I don't particularly like eager new colleagues who come up with (hallucinate) wrong answers. At the beginning, if you are uncertain, learn, and if you have questions that learning does not answer by itself, ask questions. But strongly avoid hallucinating answers. New colleagues can be taught that, LLMs not so.
