I see it the other way, that these other things have 'a language' of their own. There's vocabulary and higher structures and usages that emerge from it. I've seen this time and again. Branches of math or science, music, and even complex games (Go, Starcraft2, etc) have many layers. I can't clearly differentiate what's needed to learn one kind and not the other. A game of Go has even been called a conversation between two people.

Edit: I'm (re)learning to play Starcraft2 at a higher level and loving those 'elevated plateaus' feeling of learning which does get rare.
