In case you missed it — and how could you? — President Donald Trump earlier this week held an event with OpenAI CEO Sam Altman, Oracle chairman Larry Ellison, and Masayoshi Son, the CEO of SoftBank, to announce Stargate, a new venture that promises to invest $500 billion in U.S.-based AI infrastructure. It’s early days, but still the whole thing is somewhat nebulous. The assembled executives praised Trump for facilitating the deal, but besides providing space for a press conference, he has only said his role in all this will be aiding the effort through emergency declarations.
