In 1973 Basil Bernstein studied how UK scores in math defied class boundaries while scores in reading comprehension/essays stayed tied to them, and he developed a theory with Halliday that language embeds so much that we cannot decipher easily: dominance, status, control, land-centering, gender/mate-selection, and much more, that they assumed language was far more a social system of primate-simian signaling rather than what Shannon and classical linguists took as "communication". My guess is, LLMs are really unresolvable revelations of these hidden nuances. In a way, LLMs demand a specific language, which doesn't exist, in order to function.
