@MolemanPeter I feel like I'm unqualified to say whether it's the BASIS, but at the very least I think they're closely related. I think the key for me is that linguistics isn't about truth; even at its most rigid it's about structural correctness, and there are many kinds of structurally correct statements that are untrue. (magritte etc)
LLMs by definition work towards statistically probably structure and composition — for "truth" they rely 100% on the meaning imbued by past structure-makers
