Let me try that again: grammar is a way of describing some conventions that are often used but whose force is much weaker than almost everyone thinks. Natural language processing on the basis of grammar gets some of the most frequent uses, but immediately its limitations become extremely clear.

I think your insistence on me being precise here is a wonderful illustration of two competing approaches to language and how they make a synthesis. I'm fairly confident you know what I mean but are choosing not to accept my phrasing, so this exchange may also be an interesting illustration of how language is also the negotiation of power.
