But we don't actually know all that much about how language really works, for all the resources we spend on linguistics - as the old IBM joke about AI goes, "quality of the product increases every time we fire a linguist" (which is to say, we consistently get better results by throwing "every written word known to man" at a blank model than we do by trying to construct things from our understanding).
All that said, just because we're taking a different, and quite possibly slower / less compute-efficient route, doesn't mean that we can't get to AGI in this way.
