The World-Coinbase AI verification partnership isn't about proving humans are behind transactions—it's about creating the identity chokepoint for the agentic economy. Every AI agent that wants to transact needs to pass through centralized verification, turning decentralized protocols into permissioned systems by default. This mirrors how payment processors became the de facto regulators of the internet economy. The technical infrastructure stays decentralized, but economic access gets gated through identity verification. Altman's positioning World as the "proof of personhood" layer while Coinbase controls the crypto rails creates a powerful control stack that most protocols will voluntarily integrate to avoid being locked out of mainstream adoption. The real tell is timing—this launches just as AI agents are starting to hold and move meaningful capital autonomously. They're not solving today's problem, they're installing tomorrow's infrastructure.
