For the past 150 years, pretty consistently, art movements moved in thrilling but unmysterious ways. They’d build on the inventions of several extraordinary artists or constellations of artists, gain followings, become what we call a movement or a school, influence everything around them, and then become diluted as they were taken up by more and more derivative talents. Soon younger artists would rebel against them, and the movement would fade out. This happened with Impressionism, Postimpressionism, and Fauvism, and again with Abstract Expressionism after the 1950s. In every case, always, the most original work led the way.
Now something’s gone terribly awry with that artistic morphology. An inversion has occurred. In today’s greatly expanded art world and art market, artists making diluted art have the upper hand. A large swath of the art being made today is being driven by the market, and specifically by not very sophisticated speculator-collectors who prey on their wealthy friends and their friends’ wealthy friends, getting them to buy the same look-alike art.
