I don't see it any different to using books or other texts. It's a reference source. So- read it, consider it, fact check it, form your own opinions. I suppose basically though, 'stupid' or rather, 'cheating' students will simply copy it and/or try to pass it off as their own work. 'Clever' students will refer to it but make it clear when they are quoting. Who's opinions they agree with and why. They'll show that they read the text, understand it's context and demonstrate that they understand the meaning behind it plus, whether they agree with it.
The 'problem' with AI I imagine- more for tutors is, it will reference multiple sources I imagine plus, provide opposite theories. In my day (the olden days,) we had to source multiple books to do that and- possibly come up with the links ourselves. That in itself I imagine demonstrates intelligence. That you can think broadly around a subject and rationalise your own beliefs.
Plus, I imagine AI will constantly vary it's responses slightly. Tutors well versed in a subject in my day probably knew when a student had copied word for word from a book! I imagine with AI and all the improvisation, it must be much harder to tell.
I suppose ultimately, the question is- can a student get an AI to write an essay for them? I imagine- yes. Whether they have the tools to fully detect that though, I don't know. But, it's like calculators and everything else really. Can you do a very complex sum in your head? Likely no- because we rely on a calculator. So, most of us are more stupid when it comes to maths than previous generations. I expect the same may well happen with AI and critical thinking/ writing.
