Why AI is so centralized: How it's built, who controls it, and what comes next

A few big companies control most of the infrastructure behind AI.

Most people experience AI through a wide range of different apps that actually depend on a deeply centralized stack of data and compute. In this conversation, Ben Fielding and Harry Grieve — cofounders of decentralized machine learning protocol Gensyn — explain why this matters, and what it would take to rebuild AI as open infrastructure instead.

From unused global compute to the philosophical implications of machine intelligence, they argue that the next evolution of AI must be owned, coordinated, and verified in a fundamentally different way.
