Again, my point is not about people (maybe wrongly) reciting sentences that they have picked up somewhere without any attempt at verification or understanding of the matter. My point is making up entire new entities (function names) that don't exist at all and claiming these things as facts in a very self-confident tone. While mindlessly reciting "facts" that you have picked up somewhere as a conversational style doesn't require any understanding (it's called belief), making up entities demonstrates that you do something that requires a real understanding, but you don't have that understanding. You just somewhat carefully arrange words based on statistics to match a query. I've yet to find a human who does this. Even my uncle who fits your description more than perfectly wouldn't do this. And I've never met anyone who is mentally healthy and sober doing this.
