It also appears that society as a whole is over-optimizing using clustering in a low dimensional space. It is quite ironic to me that I will say this, as I love animation as an art form, it can convey abstract ideas that are almost impossible in any other medium. But, the world is becoming more cartoonish and flat as PCA and k-means amplify the dimensions that optimize the outcomes. Equivalence is skin deep, we wrap things in a veneer of chrome, carbon fiber and hardwoods. The message is 100% medium.
