The dissonance that I felt daily flew in the face of what Silicon Valley says about itself: that it is a meritocracy, that it values intelligence and creativity, that everyone has a fair shot if they just work hard enough.

In the ideology of the new Silicon Valley, work was for the owned. Play was for the owners. There was a fundamental capitalism at work: While they abhorred the idea of being a wage slave, the young men of Silicon Valley were not trying to tear down the capitalist system.

As a young designer explained to me bluntly: "Everyone upstairs is dumb," referring to the floor above the engineering lair at the 156 University office where customer support, administrators and salespeople sat. My first impulse was to laugh at his ridiculous, blithe dismissiveness, until I realized that it wasn't very funny.

The boys in the office preferred Daft Punk and the song "Robot Rock" as an anthem, speaking excitedly and without irony about wanting to become robots one day. That made me wonder: Why? What's the pull of being a robot?
