Yes, that is one of the points I am making. Chomskyan syntax is a strongly descriptive theory that is entirely ex post. MT and LLM systems are strongly predictive and have no descriptive theory. It is completely wrong to say the first is "understanding" and the second is not. They are both different types of understanding. In particular, Chomskyan theory clearly does not represent enough "understanding" to predict real-world English sentences with similar lucidity to that of LLMs.
