However, we now have a proof-of-concept that a computer can learn grammar in a sophisticated way, from the ground up.
We have yet to code something procedural that approaches the same calibre via a hard-coded universal grammar.
That may not obliterate Chomksy's position, but it looks bad.
Again, that LLMs can learn to compose sophisticated texts from training alone does not close the case on Chomsky's position.
However, it is a piece of evidence against it. It does suggest, by Occam's razor, that a hardwired universal grammar is the lesser theory.
LLM had really destroyed Chomsky's positions in multiple different ways: nothing perform even close to LLM in language generation, yet it didn't grow a UG for natural languages, while it did develop a shared logic for non-natural languages and abstract concepts, while dataset needing to be heavily English biased to be English fluent, and parameter count needing to be truly massive as multiple hundred billion parameters large, so on and on.
Those are all circumstantial evidences at best, a random paraphernalia of statements that aren't even appropriate to bring into discussions, all meaningless - in the sense that an open hand of a person observing another individual aligned to a line between standing position of the person to the center of nearest opening of a wall would be meaningless.
Do you even understand Chomsky's position?
To me this text look like his Baghdad Bob moment. Silly but right and noble. What else is it?
Ironically these days you can just throw this text at ChatGPT to have it debloat or critique text like this transcripts. Worse results than taking time reading yourself, but gives you validation if that is what is needed.
