Could you reproduce Silicon Valley elsewhere，or is there something unique about it？It wouldn't be surprising if it were hard to reproduce in other countries，because you couldn't reproduce it in most of the US either.What does it take to make a Silicon Valley？
    （1） ____ If you could get the right ten thousand people to move from Silicon Valley to Buffalo，Buffalo would become Silicon Valley.You only need two kinds of people to create a technology hub（中心）：rich people and nerds（痴迷科研的人）.Observation bears this out.Within the US，towns have become startup hubs if and only if they have both rich people and nerds.Few startups happen in Miami，for example，because although it's full of rich people，it has few nerds（2） ____
    Whereas，Pittsburg has the opposite problem：plenty ofnerds，but no rich people.The top Us Computer Science departments are said to be MIT，Stanford，Berkeley，and Carnegie-Mellon.MIT yielded Route 128.Stanford and Berkeley yielded Silicon Valley.But what did Carnegie-Mellon yield in Pittsburgh？And what happened in Ithaca，home of Cornell University，which is also high on the list？
    I grew up in Pittsburgh and went to college at Cornell，so I can answer for both.The weather is terrible，particularly in winter，and there's no interesting old city to make up for it，as there is in Boston. （3） ____ .So while there are plenty of hackers who could start startups，there's no one to invest in them.
    Do you really need the rich people？Wouldn't it work to have the government invest the nerds？No，it would not.Startup investors are a distinct type of rich people.（4） ____ This helps them pick the right startups，and means they can supply advice and connections as well as money.And the fact that they have a personal stake in the outcome makes them really pay attention.
