Robotics researcher argues true 3D/world understanding beats brute-force imitation learning

YuXiang, a robotics researcher with a vision/3D background, argues that a model that truly understands images, 3D, and the physical world is more likely to generalize. That's why he's skeptical of brute-force imitation learning with massive robot data — it can still overfit. He sees Astra's world-understanding approach as a meaningful contrast.
