You can buy posters and plates with pictures of Warhol, looking like the cover of a Belle & Sebastian album, with that phrase plastered across his face in Helvetica. But the full quote, taken from a 1963 interview in Art News, is a great description of how we interact on social media today.
Warhol: Someone said that Brecht wanted everybody to think alike. I want everybody to think alike. But Brecht wanted to do it through Communism, in a way. Russia is doing it under government. It's happening here all by itself without being under a strict government; so if it's working without trying, why can't it work without being Communist? Everybody looks alike and acts alike, and we're getting more and more that way.
I think everybody should be a machine. I think everybody should like everybody.
Art News: Is that what Pop Art is all about?
Warhol: Yes. It's liking things.
Art News: And liking things is like being a machine?
Warhol: Yes, because you do the same thing every time. You do it over and over again.
The like and the favorite are the new metrics of success?very literally. Not only are they ego-feeders for the stuff we put online as individuals, but advertisers track their campaigns on Facebook by how often they are liked. A recent New York Times story on a krill oil ad campaign lays bare how much the like matters to advertisers. Liking is an economic act.
