But policymakers shouldn't be trying to copy Silicon Valley. Instead, they should be figuring out what domain is (or could be) specific to their region-and then removing the regulatory hurdles for that particular domain. Because we don't want 50 Silicon Valleys; we want 50 different variations of Silicon Valley, all unique from each other and all focusing on different domains. Imagine a Bitcoin Valley, for instance, where some country fully legalizes cryptocurrencies for all financial functions. Or a Drone Valley, where a particular region removes all legal barriers to flying unmanned aerial vehicles locally. A Driverless Car Valley in a city that allows experimentation with different autonomous car designs, redesigned roadways and safety laws. A Stem Cell Valley. And so on.
