The title of this article was poorly chosen. China's "Silicon Valley dream", if it has one, is much larger than economic development among the cities of HK, Shenzhen, Macao and Guangzhou. Problems linking those cities, which is what this article is about, are unlikely to block technological development in the country. The tech hubs in Shanghai, Beijing and other fast-moving Chinese cities aren't addressed here. Moreover, even if it's hard to link those southern Chinese cities, each one of them is huge, and booming in different ways. Shenzhen along houses more than 12 million people, while the entire SF Bay Area is around 7 million.
