Masayoshi Son, the founder of SoftBank, has unveiled plans to invest a staggering $1 trillion in Arizona, USA, to construct a state-of-the-art "Crystal City" industrial complex dedicated to robotics and artificial intelligence. This ambitious venture aims to lure top-tier partners such as TSMC and Samsung Electronics, while also seeking government tax incentives to support its development. Currently in its nascent planning stages, the project holds the potential to transform into a colossal AI manufacturing hub within the United States, mirroring the success of Shenzhen's tech industry.
