I asked a lecturer some question, I think it was what happens when bit shifting signed integers.
He asked an LLM and read the answer.
Similarly he asked an LLM how to determine memory size allocated by malloc. It said that it was not possible, and that was the answer. But a 2009 answer from stack overflow begged to differ.
At least he actually tried it out when I told him.

But at this point I even had my father send me an LLM written slop that was clearly bullshit (made up information about non-existent internal system at our college), which he probably didn’t even read as he copied everything including “AI answers may be inaccurate.”
