The cultural center of Western civilization has pivoted around the arts, with science orbiting at a safe distance. Since 1937 the United States has anointed a national poet laureate but never a scientist laureate. Popular opinion has held that our era will be remembered for great art, such as jazz. Therefore, musicians are esteemed. Novelists are hip.
Film directors are cool.
The more science succeeded in creating an intensely mediated environment, the more it receded culturally. It's hard to pinpoint exactly when it happened, but it's clear that computers had a lot to do with it. What's not clear yet is what this new culture means to the original two. This new third culture is an offspring of science. It's a pop culture based in technology, for technology.
