After Elon Musk said firms involved in the $500-billion Stargate project don't have the money, Microsoft CEO Satya Nadella said, "I'm good for my $80 billion." "On the other hand, Satya definitely does have the money," Musk responded to Nadella's remark. The initial funders in Stargate are SoftBank, OpenAI, Oracle and MGX, while Microsoft is a key technology partner.
