China vs America: Who is winning the big AI battle?

These strong AI foundations were built with the help of companies such as Google, Amazon, IBM, and Microsoft which started their ascendance early. But that gap could close soon: China's tech trinity BAT is also building its AI ecosystems. There is Baidu's AI assistant/platform DuerOS, self-driving platform Apollo and deep learning platform Paddle Paddle. Alibaba has its Platform of Artificial Intelligence (PAI 2.0), the Tmall Genie voice assistant, and customer service chatbot Dian Xiaomi. Tencent has developed a cloud service, an open-source computing platform called Angel, Wechat AI, and robot reporter Dreamwriter.
