In Silicon Valley, they talk about “moving fast and breaking things”. In Washington, these days, they call it Elon Musk doing his job. The one thing even Musk, the richest human alive, is not allowed to obtain under the US constitution is the presidency, because he was not born in the United States. But when Donald Trump charged him with downsizing the entire government, Musk scored a good second best. The South African-born 53-year-old’s official title is the nondescript “special government employee”. In reality, he is one of the most powerful individuals in the country. As Trump’s top financial supporter during last year’s election, Musk emerged over the first 100 days of the new administration with extraordinary access. The bulky figure, usually wearing a T-shirt and Trump-themed baseball cap, appeared alongside the president at cabinet meetings and Oval Office sessions. On golf weekends. On Marine One. On Air Force One. And he rode that authority to launch the cost-cutting, so-called Department of Government Efficiency (Doge). Unopposed by Trump’s pliant Republican majority in Congress, and barely slowed by lawsuits, the Tesla and SpaceX magnate hit the task with the manic energy of a venture capitalist. In a shock-and-awe campaign, he ripped through official Washington, cancelling programmes, raiding secretive computers, and portraying the US government as a seething mess of fraud. At one point Musk projected a staggering US$2 trillion saving from the US$7 trillion federal budget. This then became a US$1 trillion target. And the number has quietly continued to dwindle, leaving Musk’s legacy uncertain – in more ways than one. As his Tesla car company posted a shocking 71 per cent drop in first-quarter profits on Tuesday, Musk announced he would be reducing his White House gig. But the man who wants to colonise Mars is not prone to self-doubt. Musk has appeared all-powerful and at times – as his hand-picked team of young IT wizards rampage through government computer systems – all-knowing. One of his first and splashiest moves was to send emails to 2.3 million civil servants, offering buyouts – and making clear their futures now hang by a thread. The email subject line, “Fork in the Road”, was the same as a similar email Musk sent out to employees at Twitter after he bought the social media company before drastically reducing jobs and rebranding it as X. Musk also demanded every single employee respond to a weekly email describing five things they had accomplished. This, he said, was to check staff had a “pulse”. He jokingly brandished a shiny chainsaw gifted by Argentina’s libertarian president, Javier Milei. Initial results were dramatic. Within weeks of Trump taking office, Musk’s Doge crew effectively shut down USAID, the main US foreign aid organisation. Staff at headquarters in Washington were told to go home, life-saving programmes around the world were frozen, and some government employees were stranded abroad. Other early targets included any government projects based on DEI, or diversity, equity and inclusion – anathema to the Trump government. Musk’s Doge has also tried to shut down the Consumer Financial Protection Bureau, a watchdog agency meant to guard ordinary Americans against bank malpractice, but seen in Trump world as a meddling leftist entity. In that, as in the other attacks, Doge’s modus operandi was the same: Musk’s team of outsiders entered the CFPB’s internal computer systems, taking over the financial controls and social media accounts, then locked out staff. “CFPB RIP,” Musk posted on social media. Signs are emerging after three months that Musk’s political rocket ship, at least, may finally be losing altitude. Liberals, who once saw Musk as a cult hero for overseeing the groundbreaking electric cars, now slap on bumper stickers awkwardly declaring they bought their Tesla “before Elon went crazy”. Others have taken darker routes – vandalising or setting fire to Teslas. And the company’s stock price continues to fall. Then there’s the matter of Doge’s effectiveness. Setting aside the often traumatic damage inflicted on long-standing government bodies, there is increasing doubt over the actual savings. This month, Musk announced a much smaller US$150 billion target – and even that is questionable, because the Doge website, which tracks savings, is reportedly error-strewn. Where does Musk go next? Under the law, a “special” employee can only serve the government for 130 days. So in theory Musk will have to leave this summer anyway. “He’s going to be going back” to his businesses, Trump said. “He wants to.”
