I'd agree that there is a place for complicated detail work in mathematics, but I don't think that's really what mathematics is about.

It's more about finding good conjectures, and realizing which theorems and lemmas are actually worth proving, because they say something interesting about the topic.

By analogy, it's certainly important to understand complex grammar, have a large vocabulary, etc in order to be a writer, and develop a good sense of word choice, but that's not really what writing is about; writing is fundamentally about the process by which we tell a story using these tools.
