The artificial intelligence bubble began to burst in China - investors lost 480 billion dollars. Over the past four months, the shares of the 50 largest technology companies in the field of neural networks, robotics and chips have collapsed by 40%. At the height of the hype, the field of artificial intelligence accounted for 57% of all stock market turnover, but the massive influx of inexperienced investors resulted in a sharp collapse. Now companies preparing for IPOs are forced to lower their financial forecasts.
