I love the idealism of the Web3 vision, but we’ve been there before. During my career, we have gone through several cycles of decentralization and recentralization. The personal computer decentralized computing by providing a commodity PC architecture that anyone could build and that no one controlled. But Microsoft figured out how to recentralize the industry around a proprietary operating system. Open source software, the internet, and the World Wide Web broke the stranglehold of proprietary software with free software and open protocols, but within a few decades, Google, Amazon, and others had built huge new monopolies founded on big data.

Clayton Christensen generalized this pattern as the law of conservation of attractive profits: “When attractive profits disappear at one stage in the value chain because a product becomes modular and commoditized, the opportunity to earn attractive profits with proprietary products will usually emerge at an adjacent stage.” 

Blockchain developers believe that this time they’ve found a structural answer to recentralization, but I tend to doubt it. An interesting question to ask is what the next locus for centralization and control might be. The rapid consolidation of bitcoin mining into a small number of hands by way of lower energy costs for computation indicates one kind of recentralization. There will be others.
