Do you think Microsoft would have come about if Bill Gates had got laid earlier?
Yes. Basically I think this is a false comparison. First, there's nothing saying that Sergey Brin didn't have a pile of friends -- they were probably just not the guy who made this youtube video. If you're serious about your work then you will treat it as you do anything else you enjoy. You might as well ask if Michael Jordan would have become a great basketball player if he had a bunch of friends--he probably did.

(that's the excuse I use when discussing why I'm not an internet mogul right now, heh cough)
