> Symbols, by definition, only represent a thing.

This is missing the lesson of the Yoneda Lemma: symbols are uniquely identified by their relationships with other symbols. If those relationships are represented in text, then in principle they can be inferred and navigated by an LLM.

Some relationships are not represented well in text: tacit knowledge like how hard to twist a bottle cap to get it to come off, etc. We aren't capturing those relationships between all your individual muscles and your brain well in language, so an LLM will miss them or have very approximate versions of them, but... that's always been the problem with tacit knowledge: it's the exact kind of knowledge that's hard to communicate!
