Half the world's population online by 2016

According to a new projection by the Boston Consulting Group, half the word's population (3 billion people) will be online by 2016. They predict that the Internet economy of the G-20 nations will nearly double by 2016, reaching $4.2 trillion (up from $2.3 trillion in 2010). Most of this growth will obviously be amongst the BRIC countries, with China alone having 800 million Internet users by 2016 - “about the same number as France, Germany, India, Japan, the U.K., and the U.S. combined.”  There is however no discussion of how Silicon Valley will maintain its dominance if the the majority of users are no longer in and of the Western world. Surely innovation must move to service the needs of the majority of users.
