The plot starts with the star character who wants to form a family, but when he asked adults how to have kids, they would all pull up the suspenders and sing "tralari, tralari" to evade the question.
And so the poor guy did exactly what he was told: pull his suspenders and sing, for years, to no avail.
I think LLMs are a bit like that: because they can't escape the world of text, they can't go beyond the reality that text is trying to be isomorphic to. Which means that LLMs are forced to infer answers in the context of its training data.
If LLMs were told that in order to have kids you, well, you know, right? Bees and Love? Then LLMs, asked about sex, would infer that the answer has something to do with apiculture and flowers.
