That same critique should apply to the LLM as well.
No, it shouldn't. Instead, you should compare it to the alternatives you have on hand.
The fact is,
- Using LLM was a better experience for me then reading a textbook.
- And it was also a better experience for me then watching recorded video lectures.
So, if I have to learn something, I have enough background to spot hallucinations, and I don't have a teacher (having graduated college, that's always true), I would consider using it, because it's better then the alternatives.
I just would never fully trust knowledge I gained from an LLM
There are plenty of cases where you shouldn't fully trust knowledge you gained from a human, too.
And there are, actually, cases where you can trust the knowledge gained from an LLM. Not because it sounds confident, but because you know how it behaves.
