SoftBank founder Masayoshi Son is pushing the idea of a vast $1tn artificial intelligence and robotics complex in the US state of Arizona that could include the establishment of a free-trade zone and the involvement of the world’s biggest chipmaker, TSMC.

SoftBank is seeking to launch a $1 trillion industrial complex in Arizona to build AI and robotics. The firm is also looking to team up with Taiwan Semiconductor Manufacturing Company to launch the project. The trillion-dollar project, still in its early stages, is called Project Crystal Land.

The investing conglomerate is looking to team up with TSMC on the initiative as SoftBank continues to pour money into AI.
