On March 25, according to Bloomberg News, Alibaba Chairman Cai Chongxin said at the HSBC Global Investment Summit in Hong Kong that the AI data center construction boom is showing signs of a "bubble", warning that the current investment rate has exceeded the actual growth in AI demand. He pointed out that a large number of projects have begun financing and construction before customers have been identified. Especially in the United States, technology giants plan to spend hundreds of billions of dollars, which may be suspected of being over-advanced. Cai said,"When people build data centers without explicit use of protocols, I start to worry."
