In the past twenty years, against a backdrop of crumbling infrastructure and declining trust in institutions, Musk has sought out business opportunities in crucial areas where, after decades of privatization, the state has receded. The government is now reliant on him, but struggles to respond to his risk-taking, brinkmanship, and caprice. Current and former officials from nasa, the Department of Defense, the Department of Transportation, the Federal Aviation Administration, and the Occupational Safety and Health Administration told me that Musk’s influence had become inescapable in their work, and several of them said that they now treat him like a sort of unelected official. One Pentagon spokesman said that he was keeping Musk apprised of my inquiries about his role in Ukraine and would grant an interview with an official about the matter only with Musk’s permission. “We’ll talk to you if Elon wants us to,” he told me.
