Zhang Lei, a leading AI scientist and founder of Visionary Future, argues that the current boom in "world models" within the AI industry is driven by the need to overcome the limitations of imitation learning in embodied AI. He emphasizes that a true world model must be action-conditioned, meaning it can predict environmental changes based on specific actions taken by an agent. This capability is crucial for enabling robots to learn through simulated trial-and-error, thereby reducing the high costs and risks associated with real-world experimentation. Zhang highlights that while China's hardware advancements in robotics are impressive, the true bottleneck lies in developing more sophisticated AI "brains" capable of genuine causal reasoning and adaptability, which current deep learning models have yet to achieve.
