The good news for people wanting to create the next Silicon Valley is that it’s no longer the 1950s. Globalization has changed the playing field, and the technologies that the Valley helped create have brought far-flung places and people together like never before. The Silicon Valley’s virtuous cycle has created a global supply chain in which many cities now play a critical role. Engineers write code in Bangalore, and IT specialists answer the phones in Bucharest; silicon chips are built in Singapore, and social networking companies grow in Sao Paulo. There’s no longer only room for one single place where the magic happens.
