Vitalik Buterin on Human Agency in the AI Era
Vitalik Buterin discusses the concept of 'sanctuary technologies' as a way to preserve human agency in an increasingly centralized and AI-driven world. He reflects on his personal evolution from autopilot thinking to active decision-making, drawing parallels between individual growth and technological development. The conversation also touches on the risks of cognitive erosion from over-reliance on AI tools.
Summary
In this interview hosted by Sophia Du and Benji Pandey for a16z, Ethereum founder Vitalik Buterin explores the intersections of technology, human agency, and the future of decentralized systems. The conversation opens with reflections on how the world has changed dramatically over the past decade — from bank bailouts dominating crypto discourse to now facing far more complex geopolitical and technological threats.
Buterin describes his personal journey from operating largely on 'autopilot' — passively absorbing ideologies from 1990s cypherpunks and making decisions reactively — to gradually stepping into a role of active, first-principles thinking. He recounts how Ethereum itself emerged somewhat accidentally, through a series of redirected plans involving a failed visa application, extended travel, and a rejected proposal to the MasterCoin project. Only when he witnessed the massive public interest in Ethereum did he consciously commit to it as his life's work.
A central concept introduced is 'sanctuary technology,' which Buterin defines as technology that provides safety and empowerment without being totalizing or requiring the surrender of privacy and agency. He contrasts this with a competing vision of safety — one where a centralized authority (whether a government, corporation, or AI) manages everything in exchange for control over individuals. Crypto, he argues, exemplifies the sanctuary model: it doesn't fix the dollar, but creates an alternative that individuals can freely choose.
The discussion also addresses the challenge of cognitive erosion in the age of AI. In response to an audience question about someone who noticed diminished verbal reasoning after months of heavy AI tool use, Buterin argues that humans must deliberately practice manual thinking — whether doing math without calculators, navigating cities on foot, or writing without AI assistance — to keep their cognitive faculties sharp. He frames this as fundamentally an issue of agency: the ease of deferring to AI systems makes the conscious choice to engage mentally even more important.
The overarching theme throughout the conversation is human agency — both as a design principle for technology and as a personal discipline. Buterin suggests that as the world becomes more automated and centralized, individuals must be more intentional about remaining active participants in their own lives and in shaping the technologies that govern them.
About this episode
Sophia Dew and Binji Pande speak with Vitalik Buterin about technology, human agency, and how the internet is changing the way people think, build, and relate to the world around them. Drawing from his writings and personal reflections, Buterin discusses how his worldview has evolved over the last decade, from creating Ethereum as a teenager to thinking more deeply about the social and philosophical implications of technology today. The conversation explores the idea of “sanctuary technology,” systems that provide safety and coordination without removing individual freedom or agency. They also discuss the changing relationship between humans and AI, the risks of over-relying on automated systems, and why actively learning and thinking for yourself may become even more important as AI capabilities improve. Along the way, Buterin reflects on creativity, community, identity, and the challenge of staying intentional in a world that increasingly pushes people toward autopilot.
Key Insights
- Buterin argues that 'sanctuary technology' is deliberately non-totalizing — it does not aim to transform the entire world into a safer place, but rather creates opt-in spaces where individuals retain privacy and agency, which he sees as more realistic and freedom-respecting than centralized safety models.
- Buterin claims that the dominant competing vision of safety — trusting a centralized authority (government, AI company, or foreign power) to manage risk in exchange for privacy and agency — is fundamentally disempowering and represents the core ideological threat that decentralized systems must counter.
- Buterin describes his own early years, including the creation of Ethereum, as largely driven by autopilot — reactive decisions shaped by external circumstances rather than deliberate vision — and argues that a major part of growing up is recognizing when there is 'no other pilot' and consciously stepping into that role.
- Buterin contends that actively doing things manually — navigating cities on foot, doing math without calculators, writing without AI — is essential not just for skill retention but for keeping the brain fundamentally engaged, framing this as a discipline that will only become more necessary as AI capabilities expand.
- Buterin draws a parallel between Ethereum's relationship to the dollar and the broader philosophy of sanctuary technologies: crypto cannot fix the dollar's flaws but can create an alternative free of some of those flaws, with adoption left entirely to individual choice — a model he sees as native to how decentralized technology properly functions.

One of the challenges of the world right now is that we're definitely in a less peaceful and less safe world than 10 or 15 years ago. The vision of safety that we're competing with is basically, oh, you know, let's trust the uncle in the sky and the uncle in the sky is going to figure everything out for us in exchange for taking away all of our privacy and all of our agency. Crypto does not have the ability to fix the dollar. Crypto has the ability to create its own thing that does not have some of the disadvantages that the dollar has. And each individual person is free to use it or free to not use…

Is Software Losing Its Head?
The podcast discusses how enterprise software is fundamentally shifting from being built around human interfaces to becoming 'headless'—optimized for AI agents to access data and logic directly. While incumbents like Salesforce are rebranding existing APIs as agent-ready, the real opportunity lies in new companies building between legacy vendors, leveraging AI to bridge organizational silos and capture the exceptions and context that make enterprise software truly sticky.
Don’t Follow Your Passion | Ben Horowitz’s Advice for New Graduates
Ben Horowitz argues against the conventional "follow your passion" advice for graduates, instead advocating for independent thinking and following your contribution. He emphasizes that success often creates passion rather than the reverse, and that the greatest opportunities lie in thinking original thoughts that contradict prevailing beliefs.
Technology, Alliances, and American Leadership.
A16Z partners discuss the firm's expansion into global markets, emphasizing how AI has become central to national security, economic growth, and geopolitical influence. They argue that American tech values must be preserved globally through strategic partnerships with allied nations, while addressing the dual-use nature of AI technology and the unique conditions that make ecosystems like Silicon Valley difficult to replicate.

Markus Willeck, founder and CEO of Bolt, discusses how the company became Europe's leading mobility platform by operating with superior capital efficiency, competing against well-funded rivals like Uber. He covers Bolt's expansion strategy, COVID-19 pivots, autonomous vehicle plans, and the advantages of building in Europe despite regulatory and market complexity.
Rick Rubin on AI, Creativity, and The Way of Code
Rick Rubin discusses his new book "The Way of Code," which combines 3,000-year-old wisdom from the Dao De Jing with modern concepts of 'vibe coding'—using AI as a creative tool. The conversation explores how AI democratizes creativity while raising questions about authenticity, originality, and what remains uniquely human in the creative process.
