Vitalik: Don't try to fight against AI, but instead build a sanctuary for humanity.

In the a16z podcast interview, Vitalik Buterin proposed the concept of “sanctuary technology”—not to oppose AI, but to create a parallel option that preserves privacy and sovereignty. He emphasized that in the AI era, human beings should keep a “manual mode,” avoid brain atrophy, and actively take the helm.

At a moment when AI is reshaping the world at an astonishing speed, a core question is becoming increasingly hard to avoid: is there a way for humanity to coexist with AI without being replaced? In a recent a16z podcast episode, “Vitalik Buterin on Human Agency in the AI Era,” Vitalik Buterin offered his clearest stance on AI yet—not fighting it, and not handing everything over all at once, but proactively building a “sanctuary” for yourself.

“Call on Uncle in the Sky to protect you”—the cost is giving up all sovereignty

Vitalik straight to the point identified the most dangerous mindset in today’s world. In the interview, he said directly, “Our current world is indeed less peaceful and less secure than ten or fifteen years ago.” This kind of uncertainty makes people instinctively want to find a protector they can trust—whether that’s a super AI company, Palantir, or some equivalent of a foreign government.

Vitalik calls this psychological impulse “trusting the Uncle in the Sky”:

“Calling on the Uncle in the Sky to get everything done—at the cost of all your privacy and all your sovereignty.”

The crux of the problem isn’t who that “uncle” is. It’s that once you hand over all your agency, if the protective structure changes for the worse, you’ll have no way out. During the interview, host Sophia Dew pressed further: in the AI era, will the logic of “dis-empowering safety” be amplified to an unprecedented degree? Vitalik’s answer was: of course—and that’s precisely why he’s rethinking the mission of Ethereum.

Ethereum is not here to “fix the dollar”; it’s here to provide another path

In the interview, Vitalik admitted that it took him a long time to truly figure out what Ethereum can do and what it cannot do. He gave a direct example: “Crypto can’t fix the dollar. Crypto can create something of its own—and that thing lacks some of the dollar’s certain drawbacks.”

This distinction may sound subtle, but in reality it represents a fundamental cognitive shift. It’s not about trying to hack or replace existing systems; it’s about building, alongside them, a parallel space that you can enter freely and also leave freely. He uses the term “sanctuary” to describe this design philosophy:

“Sanctuary is not totalizing. Sanctuary is not the universe.”

It doesn’t need to govern everything, and it doesn’t need to persuade everyone to join. Its purpose is to provide a small space where people can truly retain privacy and sovereignty, especially as the world becomes more dangerous and more centralized. In this context, Ethereum’s decentralized architecture and its resistance to censorship take on a more concrete meaning—not technological idealism, but the most direct engineering practice for “having an escape route.”

Dropping out, getting rejected, traveling the world: Vitalik’s autopilot years

Rarely in the interview, Vitalik looked back on a relatively private period before Ethereum was born. At 19, he joined his university’s co-op program, planning to intern at Ripple. But because the company had been set up for less than a year, his visa never came through. That unexpected off-term led him to start traveling the world as a writer for Bitcoin Magazine and visiting Bitcoin communities in different places.

Later, he presented a proposal to improve MasterCoin. When the other party said, “This will take a long time to accomplish,” Vitalik simply decided, “Then I’ll do it myself.” That proposal later became the Ethereum white paper.

However, he admitted in the interview that throughout the whole process, he had actually kept telling himself, “I’ll go back to university after a few more months,” until the following January, when he saw that Ethereum had attracted an undeniable, hard-to-ignore community size—only then did he truly accept that he wouldn’t be going back.

He called this stage “living on autopilot”—going along with the inertia of events, without an intentionally made decision. “Sometimes I’ll suddenly realize, wait, there are no other pilots at this moment.”

In the interview, host Binji Pande asked him how that turning point felt. Vitalik said it was a “scary clarity,” but also the starting point of truly taking the helm.

Six months after Claude—can you still think in real time during meetings?

When the interview moved into the segment about how AI tools affect human cognition, an anonymous listener’s question made the atmosphere feel specific and tense. The listener said, “I’ve been using Claude to write for six months, and my output has improved significantly. But last week during a meeting, I realized I can’t think in real time anymore.”

Vitalik didn’t dodge the issue, and he didn’t rationalize it away. He said directly that this is an early sign of brain atrophy. His countermeasures were very specific: from a young age, he forced himself to operate manually—no calculators in chemistry class. When walking, he didn’t use navigation; he forced himself to genuinely understand spatial relationships.

In the interview, he shared an impressive analogy: “If you’re in a car, the city you experience is a bunch of teleport points. If you walk, you have to truly think about where you’re going.”

For him, this isn’t philosophical resistance to AI. It’s purely a matter of cognitive maintenance: “Active learning is ten times more effective than passive learning, even if you spend the same amount of time. You just have to force yourself to do some things manually—even if you don’t need to—just to keep your brain switched on.”

The cryptopunk ideas of the 1990s—only truly understood in the 2020s

In the interview, Vitalik mentioned that during his teenage years, he “passively gulped down” a lot of cryptopunk ideas from the 1990s. But it wasn’t until the early 2020s that, starting from first principles, he truly re-understood the context and meaning behind those ideas.

This time gap isn’t just a personal growth story; it reveals a bigger problem. In an era when the world was still relatively stable, propositions like “privacy is a right” and “decentralization is good” sounded more like a kind of faith slogan. But once the world really became more dangerous and more centralized, the meaning of these propositions shifted—from idealism to engineering necessity.

He said that what he now understands Ethereum is supposed to do isn’t about persuading everyone to believe in a certain ideology. It’s about “helping us continuously stay in control, continuously stay in the center—some way in which we have agency.”

A sanctuary is not about staying away from the world; it’s about giving you an escape route

At the end of the interview, the two hosts, Binji and Sophia, pulled the conversation together into a shared call: when AI is reshaping social structures in ways we still haven’t fully understood, human beings need more than just tool users—they need stewards of where the world is heading—people who actively participate in shaping it.

Perhaps the best summary of what Vitalik said in the interview is this: “What we want is something that keeps us in control, keeps us in the center, in a way that we truly have agency.”

The meaning of sanctuary has never been for people to hide away inside it, and then close the door. Its existence is to give you a place to say “no” when you face the pressure of “handing everything over to Uncle in the Sky.” This is what Ethereum is trying to build—and it’s also one of the things Vitalik most wants people to remember at this point in time.
