As a Chinese, I think it's wonderful but there are some mistake with part-of-speech.

As a non-Chinese, I would love if you could expand on that comment :-)

Does it change the general point?

Well, it is obvious that the CFG model (of core grammar) is over simplified in the speech and somewhat misleading even though there is ambiguity in it. Anyway, it is just a simple talk. But I think the speaker is not really talking about programming language but more about computational linguistics...
