Elon Musk said Grok gave him a clean bill of health.
Musk told podcaster Peter Diamandis that he recently underwent an MRI. Afterward, the xAI CEO said he followed his own advice by uploading the results of a medical test to his company’s AI chatbot.
“I did an MRI recently and submitted it to Grok,” Musk said during a wide-ranging interview with Diamandis on “Moonshots” posted on Tuesday. “None of the doctors nor Grok found anything.”
It’s unclear why Musk underwent an MRI. His discussion with Diamandis, the founder of the XPrize and a Harvard-educated doctor, underscores the ongoing discussion about longevity that surrounds much of the discussion of AI’s future development.
Across Silicon Valley, tech billionaires like OpenAI’s Sam Altman and Peter Thiel are funding millions in research to combat aging and extend humanity’s lifespan. In 2024, Anthropic CEO Dario Amodei wrote that AI could double life expectancy by 2030.
Last week, Musk encouraged people to try uploading their results to Grok. He said that a Norwegian man posted on Reddit that Grok saved his life after the chatbot encouraged him to return to the hospital to get a CT scan, which confirmed that doctors had missed that his appendix was close to rupturing.
“Try it!” Musk wrote on X, quote-tweeting remarks from a February 2025 appearance on Joe Rogan’s podcast.
At the time, Musk told Rogan that AI would be “very good” at helping with medical diagnoses.
Living forever (or close to it) might not be for everyone
Musk said true immortality or close to it would be “one of the worst curses you could possibly give anyone.” That being said, the billionaire thinks it should be possible to crack the secret to staving off aging.
“I’ve long thought that longevity or semi-mortality is an extremely solvable problem,” Musk said. “I don’t think it’s a particularly hard problem. I mean, when you consider the fact that your body is extremely synchronized in its age, the clock must be incredibly obvious.”
Diamandis pitched Musk on working with Fountain Life, a longevity company that Diamandis cofounded with Tony Robbins and William Kapp. Depending on the membership tier, Fountain Life offers access to “AI-guided diagnostics” that test for biomarkers. The first goal of this branch of medicine, Kapp told TechCrunch last year, is “don’t die of anything stupid.”
“We do a 200 gigabyte upload of you, everything knowable about you, full genome, all imaging, everything,” Diamandis said, adding he did not want Musk “to pull a Steve Jobs.”
Apple’s visionary leader died in 2011 of pancreatic cancer. Jobs told his biographer, Walter Isaacson, that he regretted waiting to undergo surgery to address the cancer.
