"How would I become a VC? By being one: pull some of my own money, invest it in startups, and build my track record. That’s how. I can’t imagine any other way."
I can definitely imagine another way - the way I suppose the people that went to the event being discussed ("how to become a VC.") might have in mind: learn the ropes from someone experienced, learn what's needed (lots of legal, economical and technical stuff I didn't even know existed before reading stuff like the A VC blog http://www.avc.com/ ), learn from their mistakes and successes (and no, I don't think the Internet is a good enough substitute for the actual experience).
