World Models vs VLA: Which Approach Will Win in Embodied AI?

An in-depth comparison of the two dominant paradigms in embodied AI: World Models (predict world dynamics + plan) vs VLA (end-to-end Vision-Language-Action). Compare theoretical foundations, data efficiency, generalization, compute costs, and representative projects including Kairos, Dreamer, RT-2, OpenVLA, and ACE-Ego.
