Although it's true that in the movie women were basically presented as sex objects, and that in real life, Zuckerburg has a close and presumably non-sexual object with his COO, it's also true that the startup world is insanely male dominated. I've heard that VCs are sexist, and tend to want to fund young single white men, and I've heard other reasons given. But attempting to confine the gender imbalance entirely to the silver screen is disingenuous. We as a community really need to be doing some soul searching about why women aren't found in "man" Jose and silicon valley.
