Sean Parker is famous for many things — he had a hand in starting Napster, was Facebook's first president, a billionaire before he was thirty, and he has the most memorable line in The Social Network — a blow to the egos of newly uncool millionaires the world over.
Or, at least, his character, played by Justin Timberlake and written by Aaron Sorkin (who won an Oscar for it), has that line. Parker apparently doesn't really agree. This is from a recent interview Parker did with The Financial Times:
So is a billion dollars cool? He ponders the question carefully. “No, it’s not,” he says. “It’s not cool. I think being a wealthy member of the establishment is the antithesis of cool. Being a countercultural revolutionary is cool. So to the extent that you’ve made a billion dollars, you’ve probably become uncool.”
Whether Parker himself, a billionaire a few times over and well-known for his fancy suits and big property purchases, has avoided becoming a "wealthy member of the establishment," he doesn't speculate. He is, however, very critical of Aaron Sorkin's portrayal of him. Which is understandable, since he came off as a conniving and power-hungry party boy.
