You also have to consider that our creativity has been created by the equivalent of billions of the individuals with more computational power than the most powerful computer in the world right now, running for thousands of years of recorded history. Absolutely nothing we have done with computers approaches this, especially when you consider just how unexplored computer A.I. really is. If we call it ten orders of magnitude more "power", we're making a phenomenally conservative estimate. What could you do with a computer over a billion times more powerful than everything that Google owns?
I'd say our less-than-10-billionth computational efforts have in fact created a couple creative things. Which puts them about on par.
