Imagine being told, at an exclusive tech event, that the very lifestyle you champion is a recipe for failure. Not just in business, but in life itself. That’s exactly what happened when longevity billionaire Bryan Johnson looked a room full of ambitious founders in the eye and delivered a brutal truth.

“What founders don't realise is when you don't take care of your health, you are shitty code,” Johnson declared. His target? The cult of ‘monk mode’ and the ‘no dating until Series B’ mantra poisoning San Francisco’s startup scene. He wasn’t just criticising their work ethic; he was diagnosing a fatal flaw in their operating system.

The Forbidden Menu at a Longevity Summit

Just thirty seconds into a conversation for Business Insider’s Long Play event, Johnson suggested the open bar was an attempt to kill the audience. “The idea that alcohol is a relaxant that makes your life better is a myth,” he stated. The healthier alternative? Psychedelic mushrooms.

This set the tone for an evening that would weave together defence tech, AI, and a very candid masterclass on human biology. Johnson, 48, was there with his girlfriend and cofounder, Kate Tolo, 30, to preach a gospel of optimisation that extends far beyond supplements and sleep trackers.

Why He’s Writing an "Instructional Manual" on Sex

Another pillar of his longevity protocol? Have more sex. Johnson has been posting vividly about his sex life with Tolo on X, not for titillation, but as public service. He told the audience he’s effectively “writing an instructional manual on how to have sex,” arguing too many people need the guidance today.

In a city known for celibacy-as-a-badge-of-honour, his message was a direct provocation. He compelled the room to put themselves out there, framing romantic connection not as a distraction, but as a critical component of high performance.

A Conversation Unlike Any Other

The discussion grew more animated, arguably marking the first time in conference history where defence tech, AI-accelerated income inequality, cervical tenting, and clitoral erections were debated on the same stage. Johnson’s philosophy is a total system overhaul, where every input—from your drink to your relationships—is optimised for output.

For the founders in the room, the takeaway was stark. The relentless grind they wear as a badge of honour might be the very thing sabotaging their potential. Johnson’s warning suggests that in the race to build a unicorn, they’re neglecting the most important asset: themselves. The future of business, it seems, belongs to those who are built to last.
