I would beg to differ. Most of the people I know of high intelligence seem to be a jack-of-all-trades, with almost all of them having, if not a heavy love of language, a decent dollop of it.

Ultimately, there is art and creativity in everything, you just need to know where to find it. The type of creativity that creates a stunning artistic composition is the same sort of creativity that creates a masterful Rube-Goldberg system, and the same sort of creativity that creates complex formulas to describe and generalize real life occurrences. Your brain knows the constraints, sub-patterns, and has an array of tools that allow it to intuitively define the form, and you go through processes to fit it.
