Jeff Towson's visit to WAIC 2026 revealed a clear shift from the document era to the build era, where ideas can be executed immediately. His first takeaway is the rapid convergence of robots and AI, with 30% of the conference dedicated to robots, particularly humanoid and consumer-facing models, all discussing their embodied AI systems. The second takeaway is the intersection of world building, 3D modeling, and video generation, which combines physics and training to create digital assets for robot training. The third takeaway highlights Tencent's rapid product cadence and user-friendly approach. Finally, he notes a Cambrian explosion of combinatorial innovation, exemplified by creative products like smart guitars and soccer-playing robots. Jeff contrasts Chinese AI entrepreneurs who advocate for democratizing intelligence through open-source, low-cost models with OpenAI's profit-driven shift, and notes a potential U.S. government ban on Chinese open-source AI models.
