Longevity expert Bryan Johnson recently appeared on This Past Weekend podcast with comedian Theo Von, where he discussed his controversial ideas about extending human lifespan and how AI could help with it.
Johnson began by drawing a historical comparison to illustrate how revolutionary ideas are often dismissed before they become widely accepted. “In 1870, the big talk of the town was there was this divide over this guy who had ideas that the reason why people were getting sick and passing away is because of these microscopic objects called bacteria. And half the town was like, ‘That’s not possible. What are you talking about?’ The other half was like, ‘Honestly, that could be legit.’”
Using that example, Johnson suggested that humanity may now be at a similar turning point with longevity science. “The idea I’m basically suggesting to the world is that we’ve reached a point of humans on the planet where we may not d*e… We might be able to extend our lifespans to horizons where we can’t really imagine. For example, like 150, 200, 500, a thousand, like some number we don’t even know. We are at that point with technology. We may be the first generations of humans who don’t d*e.”
He also criticized what he views as systemic incentives that work against human health. “Fast food companies like McDonald’s and Wendy’s, they use science to make food that adds you to their food. They’re building a*diction. Social media algorithms, they’re building a*diction. As a society, we have a predator prey relationship where companies prey upon individuals with the best science and technology possible and extract from them life for profit.”
As part of his ongoing personal experiments, Johnson shared details about testing his body for microplastics and the surprising results that followed.
“We measured microplastics in my blood and we measured microplastics in my s*men. We wanted to look at se*en because fertility is really important. One hundred percent of tested men have microplastics in their balls and their s*men.”
According to Johnson, lifestyle interventions appeared to make a measurable difference: “We dropped my microplastic burden by 87% in both blood and semen. We think dry sauna was potentially the cause of reducing microplastics in the body overall.”
Johnson also explained that his widely publicized health regimen is ultimately tied to a larger goal connected to artificial intelligence. “What a lot of people don’t know is this entire project I’m doing is about AI. It’s not about health.”
To illustrate his thinking, he described imagining how future generations might look back at the present moment. “There they are talking, and they’re reflecting on the early 21st century, our time, and they’re saying, ‘We appreciate homo sapiens that lived in the early 21st century because they did blank that allowed intelligence to still exist in the universe.’ I think they say two things. One is that’s when homo sapiens gave birth to super intelligence. The second thing is they say they figured out that they wouldn’t d*e.”
Discussing the transformative potential of advanced artificial intelligence, Johnson compared its capabilities to traditional ideas of divinity. “When we talk about God, we say God’s omnipotent. On some kind of time scale, AI is kind of that. When you actually have the potential of building billions of gods or godlike powers, why wouldn’t you immediately level up your ambition by like a thousand X?”
He concluded by outlining what he believes could be humanity’s most important goal as AI becomes more powerful: establishing a shared agreement for survival.
He stated: “The single thing that every human agrees to in this moment is nobody wants to d*e right now. What I’m saying is the obvious answer we say to AI is we want to exist. That’s our goal. You’re trying to basically just get a peace accord with all humans and all AI and say, ‘Can we just strike a deal where we have the right to exist?’”
