Elon Musk is back to thinking on a scale that feels bigger than just the next product launch or even the next decade. This time, he’s talking about ageing itself and whether science could eventually slow it down, stop it, or even reverse it altogether. Speaking at the World Economic Forum in Davos, the Tesla and SpaceX boss said growing old isn’t some unknowable mystery. According to him, it’s a problem humans will crack sooner or later.

During a conversation with BlackRock CEO Larry Fink, Musk made it clear that he doesn’t see ageing as anything magical or impossible to understand. In his view, once researchers identify what actually causes it, the answer may turn out to be surprisingly obvious.
“When we figure out what causes ageing, I think we'll find it's incredibly obvious. It's not a subtle thing,” Musk said.
To explain why he thinks this way, he pointed to how the human body ages as a whole rather than in isolated parts. “I've never seen someone with an old left arm and a young right arm ever in my life,” he said, suggesting there must be some kind of internal system or clock that keeps all the body’s cells ageing in sync.
What made these comments stand out even more was their timing. Just days earlier, Musk had sparked online discussion by talking about a very different idea of immortality, one that has nothing to do with keeping the body young.
That earlier conversation happened on X, where Musk was discussing Grokipedia, a proposed AI-driven knowledge platform being developed by his company xAI. The idea revolves around people uploading their life stories, memories, and experiences into a massive digital archive. Over time, this data could be copied and sent beyond Earth, possibly to the Moon, Mars, or even farther into space.
In that scenario, your physical body doesn’t last forever, but your experiences do. Even if humanity were to disappear someday, Musk imagines these records still floating through space, waiting to be discovered. Reacting to the idea online, he summed it up with a line that instantly went viral: “Immortality can be yours!”
Back at Davos, though, Musk took a more reflective approach when talking about extending physical life. While he said reversing ageing is “highly likely” in the long term, he also admitted that living much longer could come with real consequences.
“There is some benefit to death, by the way,” Musk said. He explained that if people lived for extremely long periods, societies might stop evolving. Power structures, ideas, and systems could become rigid, making the world feel stuck. “It may become stultifying,” he warned, pointing to the risk of losing creativity and momentum over time.
Interestingly, Musk’s presence at the World Economic Forum itself was a surprise. This was his first time speaking onstage at the event, which he had earlier brushed off as “boring af”. While the conversation with Larry Fink covered a wide range of topics, Musk didn’t go into specific timelines or technical details about how ageing might actually be reversed.
For now, his comments sit somewhere between bold speculation and long-term optimism, very much in line with Musk’s habit of looking far beyond the present and imagining futures most people aren’t even thinking about yet.
