I recently read a rather interesting story about Bryan Johnson that made me think. This guy is practically the definition of a “radical career pivot.” He founded Braintree in 2007, grew it by 4000% per year, sold it to PayPal in 2013 for $800 million (he personally took home $300 million), and instead of staying in traditional fintech, he became completely obsessed with anti-aging. His stated net worth is around $400 million, but what he does with his money is truly out of the ordinary.

The interesting part is that Johnson was actually one of the early believers in cryptocurrencies. While he still owned Braintree, he was working on a partnership with Coinbase to let merchants accept Bitcoin. He was very optimistic, then he sold—and, well, he said candidly that in a parallel universe he would have dedicated his entire life to crypto. Not bad as a “what if.”

Now I find him in Singapore at Token2049, where he’s helping launch The Network School together with Balaji Srinivasan, the former CTO of Coinbase. They’re trying to bring together 150 “capitalist libertarians” focused on tech in a ghost city built by Chinese people on an artificial island in Malesia. The idea is to create a “Network State”—basically a concrete realization of libertarian values and Bitcoin-based finance.

But the craziest thing about Bryan Johnson’s wealth and vision is how longevity has become his new obsessive project. He spends a couple of million dollars every year on his Blueprint program, has a team of 30 people (nutritionists, MRI specialists, the whole thing), and lives by regimes that seem like they were pulled straight from a dystopian film. He eats his last meal at 11 a.m. to optimize sleep, does 35 different exercises, and measures everything. The result? He says his aging speed is 0.64, meaning biologically he celebrates his birthday every 19 months instead of every 12.

This is where the story gets even weirder: Johnson firmly believes that biological immortality is “solvable.” The immortal jellyfish exists in nature and can regenerate indefinitely, so in his view it’s just a matter of applying the biology that already exists to humans. He takes 1500mg of metformin per day (research on primates shows it can reverse six years of brain aging), he’s enthusiastic about Ozempic, and he sells a series of supplements online under the Blueprint Stack brand.

What’s fascinating is how all of this connects to his vision of Bitcoin and superintelligence. For Johnson, Bitcoin rejects inflation—the state that slowly drains your wealth. Don’t Die (his longevity project) rejects aging—the state that slowly drains your health. They’re parallel tracks of the same libertarian philosophy. He isn’t afraid of dying, but he wants to stick around long enough to see how AI transforms human civilization.

Some observers have noted that the Don’t Die movement has almost religious aspects—principles like “not dying as an individual,” “not harming each other,” and “not dying as a species.” Johnson, who grew up Mormon but lost his faith, has admitted that yes, he’s building an ideology on par with capitalism or Christianity—something that answers the questions posed by emerging technology.

The most fascinating part? Johnson is convinced that most of the benefits of longevity come from ordinary things—diet, exercise, sleep—but people don’t do them because they prefer to believe in miracle drugs. Meanwhile, his personal wealth funds experiments that could redefine what it means to age. Whether you find him brilliant or completely insane, one thing is certain: Bryan Johnson’s wealth is no longer just money—it has become a whole vision of the human future.
