Well that may explain it, then, thanks for letting me know.
I realise that my question was not super clear because... well I didn't really know what to ask :-). I was just trying to engage in a human interaction. Say I am at a party with friends and strangers, and when I get introduced to a stranger, they say "I am a professional reverse engineer". Because I find that interesting, I will start asking questions. And I may well start trying to explain what I find interesting, giving the expert an angle to start talking about it.
Of course I could just go home and read about reverse engineering. But at that moment, in that party, I want to enjoy a discussion about it with a human being. Part of the experience is that I get to hear what some other human thinks about it.
I am not there for a formal course, I am there to listen to what a human being has to say about it. And obviously an LLM cannot do that job :-).
