I can see the appeal of that kind of thinking. Babies learn words by repeating them without knowing what they mean. They gradually learn the meaning of words by trying to use them and getting feedback. But LLMs are not trying to "use" their language for any particular purpose. They just idly chat on, like a machine :-)

It is possible to repeat words and sentences without having any idea of what they mean. I think the LLMs are currently at that stage.
