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.

Kai-Fu Lee is the chairman of Sinovation Ventures and the president of its Artificial Intelligence Institute. He was the founding president of Google China. He recently spoke about his new book, "AI Superpowers: China, Silicon Valley and the New World Order," with The WorldPost's editor in chief, Nathan Gardels. WorldPost: Artificial intelligence is surely the most consequential technological development of the 21st century. In your book "AI Superpowers," you've written the most comprehensive global account of artificial intelligence to date. What are the central themes of your book?

This is the weekend roundup of The WorldPost, of which Nathan Gardels is the editor in chief. Technology is not a neutral tool. Its use is infused with the cultural ethos of those who deploy it. Digital connectivity may have been conceived in the algorithmic imagination of Silicon Valley libertarians as a way to free the individual from institutions. But in the hands of China's institutional civilization, shaped for millennia by a communitarian and authoritarian mindset, it further empowers the state.

Nicolas Berggruen is chairman of the Berggruen Institute and publisher of The WorldPost. Will super-intelligent machines be our servants or masters? This is a misleading way of thinking because it treats artificial intelligence and humans as if they were fundamentally separate categories. Instead, what seems to be emerging is something more like human-AI hybrids, extending and transforming our cognition and consciousness. We see the first traces of these hybrids in everyday experiences such as driving around with digital mapping technologies, which have reshaped our sense of space.
