From World Model to Domain Intelligence

Building on Jack Dorsey and Roelof Botha's 'world model' concept for AI-driven company intelligence, this piece argues that a single unified company world model will face the same scaling problems as software monoliths. The proposed solution is a domain model architecture — specialized AI models for Revenue, Marketing, Product, People, and other domains — each paired with a human domain expert who provides judgment and taste. These domain models deliberate with each other to surface cross-functional insights. A unifying 'Operating Mind' layer enforces strategic coherence across all domain models, acting as a constitutional layer rather than a command-and-control system. The piece also explores how leadership roles evolve: information routing disappears, while domain expertise, strategic judgment, and the ability to shape AI model intent become more valuable.
