(Bloomberg) -- It was hard to tell whether hope or fear was the predominant sentiment about the future of artificial intelligence, according to a panel discussing the state of the field at the World Economic Forum in Davos, Switzerland, Wednesday. A.I. systems are rapidly becoming more capable, the panel — which included Ya-Qin Zhang, president of Chinese search engine company Baidu Inc., and Matthew Grob, the chief technology officer at Qualcomm Inc. — agreed: they’re able to learn from analyzing large data sets and they can increasingly discern human emotions by monitoring facial expressions and natural language.
