Investors have long warned that the collapse of the global artificial intelligence bubble is imminent. Now Reuters writes that in China it has "already broken out". China's Star 50 stock index, which is dominated by companies related to neural networks, is down 40% from its peak in July, it said: "The collapse could hinder investments in the technology sector and new companies going public." The Star 50 index includes leaders in the field of artificial intelligence and semiconductors. A 40% collapse in less than four months and the loss of approximately $480 billion in market value "is a bad sign for already volatile global markets," the agency adds. He also quotes one fund manager in Beijing: “The stock market has become a crazy speculative bull market*. And now we see the bubble bursting." The collapse of the artificial intelligence bubble was predicted in the past, among others, by the investor Michael Burry, who predicted the mortgage crisis in 2008. There was also a warning from the International Monetary Fund: a possible collapse of stocks of artificial intelligence companies could damage the entire global economy. * A bull market is a period when the prices of various assets rise over time and with confidence, and optimistic forecasts prevail among stock market participants.
