Crypto once attracted nearly every top engineer wanting to build a new system. Now, that tide is beginning to shift toward AI. Sam Blackshear, co-founder of Mysten Labs and one of the minds behind Move, has just announced he’s joining Anthropic to work on AI security. Previously: + Blockchain was a new problem to solve. + Smart contract security was severely understaffed. + Layer 1s competed primarily on engineering talent. Today: + AI generates code faster than humans. + Attack capabilities are escalating in tandem. + Security has become a race between models themselves. What’s noteworthy isn’t just that a CTO is leaving a project— It’s where the world’s top engineers are choosing to spend their next few years. Narratives usually follow capital. But talent often leads both.
