Elon Musk has plenty on his plate—rocket launches, electric vehicle production, social media drama. But when asked what keeps him up at night, his answer was surprisingly specific: artificial intelligence.
During a December episode of "The Katie Miller Podcast," the Tesla CEO didn't hesitate. "AI. Yeah, actually," he said. Then he went further: "I've had a lot of AI nightmares… many days in a row."
This isn't your typical CEO anxiety about quarterly earnings or competitor threats. Musk is talking about something deeper, something he's actively building but can't fully control.
A Future Where Work Becomes Optional
The conversation started when Miller brought up Musk's previous claims that people might not need to work in the future. Musk confirmed he still believes that. "Assuming the current trend of artificial intelligence and robotics continues, which seems likely," he explained, "the AI and robots will be able to do anything that humans want them to do."
He paused, then added: "Hopefully not more than that."
According to Musk's vision, we're heading toward a world where machines don't just assist with labor—they replace it entirely. AI and robotics will provide every good and service society needs. "Work will be optional," he said. "People will be able to do whatever they want with their free time."
But here's where it gets interesting. Musk made it clear this isn't a future he's championing. "I just want to separate out from what I wish would happen versus what I predict will happen," he said. "People get confused about that. They think that what I predict will happen is what I want to happen."
The Man Who Can't Hit the Brakes
Then Musk addressed the elephant in the room. "If I could, I would certainly slow down AI and robotics," he admitted. "But I can't."
The technology is advancing "at a very rapid pace — whether I like it or not," he added.
These comments carry unusual weight because Musk isn't observing from the sidelines. He co-founded OpenAI back in 2015 alongside Sam Altman with the stated goal of developing AI that would benefit humanity. Musk left the company in 2018, citing potential conflicts with Tesla's AI work and disagreements about OpenAI's direction.
In 2023, he launched xAI as a direct competitor to OpenAI, Google DeepMind, and Anthropic. xAI's chatbot, Grok, is already integrated into his social media platform, positioned as a "maximum truth-seeking" alternative to mainstream AI models.
At Tesla, AI isn't just a side project. The company's Full Self-Driving system depends on large-scale neural networks trained on massive amounts of real-world data. Musk has also pushed aggressively into humanoid robotics with Tesla's Optimus project, which he's said could eventually perform physical labor in factories, warehouses, and homes. At Tesla's annual shareholder meeting last month, Musk even suggested that robots could one day reduce the need for prisons by intervening before crimes occur.
That context makes his nightmare comments harder to brush off.
Where the Fear Lives
When Miller asked where those fears manifest, Musk answered directly. "If you say, where do I wake up in nightmares? Oh — AI. Yeah. Actually."
Later in the conversation, Miller asked about irrational fears. Musk said he doesn't entertain them. "I try not to have irrational fears. If I find an irrational fear, I squelch it," he said. "I don't believe fear is — fear is the mind killer."
Notably, he didn't categorize his AI concerns as irrational.
Racing Ahead of the Guardrails
The timing of these comments matters. AI systems are being deployed faster than regulatory frameworks can keep pace. Governments are still debating what guardrails should look like. Companies are racing to release larger and more capable models. Investment in AI infrastructure has surged into the hundreds of billions, and the technology is already reshaping software, transportation, education, and creative industries.
Musk sits at the center of that acceleration—building it, funding it, competing in it—while openly acknowledging that the outcome is uncertain.
During the podcast, Musk mentioned he averages six hours of sleep per night. "I tried having less than six hours sleep, but… my cognitive function is reduced," he explained. Six hours is his baseline—and lately, even that seems to come with AI running in the background.
It's an unusual position: a tech leader driving some of the most ambitious AI projects in the world while simultaneously admitting those projects give him nightmares. Most founders talk about their vision with unqualified optimism. Musk is building the future while worrying about what happens when it arrives.
