if you haven't taught someone who is helplessly addicted to LLMs, LLM brain is so much worse than you can possibly imagine. the problems i'm seeing from someone i am currently teaching are indistinguishable from illiteracy - this person literally cannot read single-line, fully descriptive error messages, and proceeds to just copy and paste whatever they say into the chatbot and copy/paste whatever it spits out, and in this problem domain the LLM is wrong nearly 100% of the time. when i ask them to stop and think about what the problem is, what steps they might need to take to diagnose and resolve it, and how does that fit in with the context of what we've been doing together for >6 months, they literally can't.
Edit: Oop this post escaped containment. I am not implying that it is impossible to learn with an LLM, so if it works for you then that is basically irrelevant to my description of this one very specific pattern of learning with which I have direct and repeated experience. This person is otherwise very smart and competent, I am describing the impact of the LLM on their mode of learning the things I am trying to teach them.
