This is the weekend roundup of The WorldPost, of which Nathan Gardels is the editor in chief. In The WorldPost this week, we examine and evaluate two key developments of the digital age: the emergent geopolitics of artificial intelligence and Facebook's recent move toward "reputational scores" as a means to signal trustworthy information to users. For Lee, who is based in Beijing, the world of AI has become a "duopoly" in which China and America competitively drive each other's innovations forward while dominating the rest of the world. Lee argues that China's "scrappy" days of stealing intellectual property to get ahead are behind it. Rather, its rapid advance in AI today is due to the superior business model of its tech entrepreneurs.
