From my 2010 movie review of The Social Network:

There’s much debate in the press about how realistically the film portrays the tycoon. The obvious answer is that [screenwriter Aaron] Sorkin is projecting onto Zuckerberg his own (perhaps not wholly undeserved) self-loathing over sex, drugs, and ethnicity. 

In Sorkin’s imagination, Silicon Valley looks like Jim Morrison’s Laurel Canyon in 1969, with barely legal stoned groupies swarming over the nerds. (The reality is that Zuckerberg has had the same unspectacular girlfriend, to whom he appears devoted, since he started Facebook. Monogamy is a huge time-saver.)
