Your brain runs on 20 watts — less than a dim lightbulb. Modern AI clusters consume megawatts and still can't match what those 20 watts produce. Architecture under constraint explains the difference. The brain can't request more compute or expand its memory with hardware upgrades. Those hard limits forced evolution to build something elegant: billions of simple components following local rules, fault-tolerant, self-repairing, capable of creativity with almost no overhead. Money follows the same design split. Fiat operates like an AI cluster — central banks, regulators, commercial banks, courts, and political bodies all adjusting levers in real time. Massive institutional overhead producing monetary signals that still get noisy and distorted. Bitcoin operates like the brain. Fixed rules, fixed supply, decentralized validation. No committees reinterpreting policy. A difficulty adjustment that keeps the system balanced regardless of external conditions. The most capable systems have never been the ones with unlimited resources. They're the ones where constraints force elegance.
