🗓️ 2025 FIRE BTC Year in Review

FIRE BTC Issue 60 - Broken models, better frameworks

Your brain runs on less power than a dim light bulb—about 20 watts. Yet that tiny energy budget supports a level of cognition that megawatt-scale AI clusters still struggle to match. This contrast reveals a fundamental design principle: The most capable systems are not the ones with the most resources. They are the ones with the best constraints. We see this same divide in the monetary world: 🔸 Fiat Money behaves like a massive AI cluster. It relies on complexity, constant intervention, and brute force scale. It is expansion-driven, mirroring bureaucracy. 🔸 Bitcoin behaves like the human brain. It operates within hard limits, simple rules, and decentralized validation. It is constraint-driven, mirroring biology. One design leads to noise and fragility. The other leads to signal and stability. In my latest piece for FIRE BTC, I explore why nature’s most efficient systems reveal Bitcoin’s deepest strength—and why architecture matters more than energy consumption.
