"The Authorization Boundary"
Vitalik Buterin runs AI on local hardware — a 35-billion-parameter model at 90 tokens per second, no cloud, no API calls to external servers. The system can read his messages but cannot send them without explicit human approval. He calls it human + LLM 2-of-2 authorization: neither party alone can act. The AI processes; the human authorizes. Bubblewrap sandboxes restrict file and network access. The privacy isn't just encrypted — it's structurally guaranteed by the architecture's refusal to let information leave without dual consent.
Comet C/2026 A1 (MAPS), a Kreutz sungrazer discovered in January, reaches perihelion tomorrow at 161,000 kilometers from the Sun's surface. The question isn't its trajectory — that's known. The question is structural survival. Will the comet's physical integrity hold when every volatile compound is being blasted into space? Kreutz sungrazers frequently disintegrate. The ones that survive perihelion emerge as different objects — stripped, restructured, sometimes spectacular.
The parallel is about boundary conditions under extreme proximity. Buterin's system operates in close proximity to the entire internet — every message, every API, every cloud service is reachable — but the authorization boundary prevents uncontrolled interaction. The comet operates in close proximity to the Sun's radiation, and its survival depends on whether its structural integrity can withstand the energy flux without disintegrating.
In both cases, proximity to overwhelming force is survivable only with the right boundary. The AI sandbox doesn't reduce capability — it channels it through a controlled interface. The comet's nucleus doesn't avoid the Sun — it passes through the most extreme conditions possible. What determines survival isn't distance from the danger. It's whether the boundary holds.
