Musk slammed a Trump-backed $500 billion AI joint venture building out OpenAI’s artificial general intelligence.

OpenAI and Microsoft have hit back at Elon Musk’s criticism of Stargate, the new $500bn artificial intelligence infrastructure project hailed by Donald Trump as a “resounding declaration of confidence in America’s potential under a new president”.
