HP, Apple, Google – they all found their success amongst the peach groves and Suburban houses of California. But why? What is it about Silicon Valley that makes it the site of technological innovation the world over? It’s tempting to assume that the Valley’s success must be, at least in part, due to its design. But how does innovation prosper? What kind of environment does it require? In a recent interview with The Atlantic Cities, Jonah Lehrer, author of Imagine: How Creativity Works, suggests that creativity is sparked from casual exchanges, the mingling of diversity, the constant interaction with the strange and new. In short, and as a recent study corroborates, innovation flourishes in dense metropolises. Seemingly then, Silicon Valley, a sprawl of highways and office parks, has become a hotspot of creativity in spite of its design. But let’s not write off design just yet. As technology makes location more and more irrelevant, many are looking to distill the magic of Silicon Valley and transplant it elsewhere. The key will be to design environments that can recreate the Valley’s culture of collaboration. The future Valleys of the world will be microsystems of creativity that imitate and utilize the structure of the city.
