@emilygorcenski I see a third possibility (speculating outside my competence): what if Chomsky was onto something with his concept of a "deep grammar" underlying human languages, and LLMs have inadvertently exposed or replicated it.
But language and linguistic competence alone are not actual intelligence or sentience—they're just how intelligence communicates.
(Which is where the illusion arises.)
People who've never seen a picture of a face see one for the first time and think it's a face.
