Today’s digital world is organized around two centers of gravity: the U.S. West Coast and the east coast of China. These gold coasts are home to nine of the top 10, and 18 of the top 20, internet companies, as measured by market capitalization. The leading companies in online search, social media, and e-commerce are all based in one or the other of these two regions. But as the digital revolution continues to spark widespread disruption in other industries — automotive, financial services, health care, and retail — who will win? As other nations consider their own stakes in the game, and as incumbents engage with digital disruption, will the two centers of gravity hold, or will the gains be more widely distributed?
