Elon Musk’s artificial intelligence tool Grok was used in strikes against Iran, the United States government revealed in a legal briefing seen Tuesday by AFP. The June 15 brief defends the gas turbines used by a giant data centre belonging to the trillionaire’s company xAI, which are the target of an environmental lawsuit. In the brief, the US Department of Justice argued that the lawsuit “threatens American national, economic, and energy security by seeking to shut off the power supply for artificial intelligence innovation that supports the Department of War’s military operations”.
