I was surprised to hear an otherwise knowledgeable person participating in the Grand Challenges discussion here at University of Washington say there was no innovation in China. The time and place were not right for that discussion. But then NYT came with a substantive refutation:
Snapchat and Kik, the messaging services, use bar codes that look like drunken checkerboards to connect people and share information with a snap of their smartphone cameras. Facebook is working on adding the ability to hail rides and make payments within its Messenger app. Facebook and Twitter have begun live-streaming video.
All of these developments have something in common: The technology was first popularized in China.
