Probably proof that who you know is about as important as what you can do, if not more
I view it more like an instance of synchronicity, where a lot of bright young people looked at the world independently and decided that this was the space they wanted to be working on. And then when that space didn't pan out they went their separate ways, but the fact that they were bright & energetic meant that the successor projects became huge.
(I wonder if a similar effect explains the General Magic, Paypal, and Justin.TV mafias.)

I’m sure there were great synchronicity of people working on squaring the circle in 18th century, and of people working on the philosopher stone earlier, except they were all misguided so we don’t talk about them.
