Feel spoiled by Silicon Valley

Today I read the article from NY Times that explains how the Paypal alumni network creates so many successful companies like YouTube, Slide, and etc. I also read some people from around the world are complaining they lack resource, either technology or finance, in their countries or cities. Yes, Silicon Valley is great. If you get a cool idea, you can always find some smart guys working with you. If you want some technology know-how, through your network you can always reach some person having that expertise. Guy has said this advantage in a more marketing-person way. Silicon Valley is great is because it is not as hot as Hiwaii, not as cold as New York.
Anyway, after Paypal was acquired, we didn't see any innovation. Mobile payment is a long waiting feature. That's why those energetic Paypal aluni left and started own venture. I am pretty sure as Google becomes bigger, its code becomes aging and difficult to upgrade, its innovation will become slow. It is always easier to draw a more beatiful picture on a white paper than on a highly polluted canvas. Google prefers hiring fresh grads. When Google is slow on innovation, I am pretty sure those guys will quickly becomes Google alumni and change Silicon Valley again. At least, they've got money and talent.
