No reason we can't rely on other sensory modalities after the AI "gets good enough," either. Humans don't have LIDAR, but that doesn't mean that LIDAR is a "cheat" for self-driving cars, or something we should try to move past.

In principle, I agree; but remember that people like to save money, and that includes by not spending on excessive sensors when the minimum set will do.

What I think went wrong with Musk/Tesla/FSD is that he tried to cut costs here to save money before it would actually save money.
