This treats human language as a somewhat static thing that can be fully specified. Which, interestingly, avoids a large portion of human languages in poetry and metaphor. A bit like judging story telling by only accounting true stories, thus completely ignoring all of fiction. Saying nothing of false stories purported as true.

It is quite possible that understanding is nothing more than a statistical relating of otherwise unrelated things. Some things, we accept as being 100% related. But, quite a lot of things are just "highly related." Where "highly" is probably not specified.
