ON UNIVERSE, LIFE, AND AI

Ivan Zhao frames AI as the latest “tool of life” after language, markets, and the internet. Humanity uses culture, capital, and computation to impose its values on an indifferent universe, and AI extends this by accelerating idea discovery and coordination. In this view, AI is not separate from life but a continuation of life organizing matter and energy through intelligence.

INTRODUCING EVMBENCH

EVMbench is a benchmark that evaluates the ability of AI agents to detect, patch, and exploit high-severity smart contract vulnerabilities. Smart contracts routinely secure hundreds of billions of dollars in crypto assets. As AI agents improve, it becomes increasingly important to measure their capabilities in economically meaningful environments. This also means using AI systems to defensively audit and strengthen deployed contracts.
