Artificial intelligence (AI) is on the verge of becoming a'bubble' in China as a large influx of money and talent heat the market, analysts and experts warn. "For the job market in China's AI sector, I see a bubble already exists now. Some practitioners in the AI industry and are paid salaries that are unfairly high," said Wang Xiaochuan, chief executive officer of Chinese internet company Sogou. "Investors expect too high a return on their investments, and the valuations of China's AI enterprises are much more expensive than those in the US." In terms of investment in AI enterprises, China was in second place in 2016 on US$2.6 billion, followed by the UK on US$800 million, according to data from Chinese think tank WuZhen Institute.
