This is a really thought provoking article. I especially like the reference to the movie The Devil Wears Prada, because in essence, what is being described is a very complex algorithm embedded in a large group of people observing a lot of things (fashion trends). The question raised in my mind is this: where is the tipping point at which the answers / predictions in that algorithm become stale or shift rapidly and require an answer that is orthogonal to previews answers (!) but still "correct". This tipping point seems to be what taste is about to some degree. ..so now we need an algorithm to predict the tipping point; its algorithms all the way down.
