Steve Wozniak isn’t a fan of Elon Musk, and he’s not afraid to say it. The Apple cofounder recently spoke to CNBC and shared some blunt opinions about Musk—both as a CEO and now as the guy in charge of cutting costs in the federal government.

“I don’t know what got into his head,” Wozniak said, talking about Musk’s role leading the Department of Government Efficiency (DOGE). “Sometimes you get so rich at these big companies, when you’re on top, it goes to your head, and you’re the most credible person in the world, you’re the brightest, and you’re gonna dictate what others will do.”

Musk has built a reputation for shaking up industries—electric cars, rockets, and even social media. But now, as the government’s efficiency expert, Wozniak thinks his approach is more about force than finesse.

“Bullying is the best way to think of it,” he said.

Musk’s cost-cutting efforts have been controversial. Critics, including government workers and legal experts, say he’s making cuts without really understanding what’s at stake. Reports say some of the so-called savings come from contracts that had already ended or jobs that had to be reinstated. The government has even reversed some of the layoffs, bringing back employees at the CDC, FDA, and even the agency that handles nuclear safety.
