From Chatbots to Reality Engines: AI's Next Competitive Frontier

World models mark a fundamental shift from generating outputs to simulating environments where AI can plan, test, and reason about consequences. This evolution unlocks capabilities essential for robotics, spatial computing, and design—domains where simulation fidelity matters far more than language fluency. Rather than converging on one approach, the field is fragmenting into specialized architectures, suggesting the winners in next-generation AI will master domain-specific simulation engines rather than universal models.
