A model that performs strongly in a test environment will eventually be deployed in the real world, and the physical world isn't always agreeable; surfaces are uneven, sensors are noisy, and people wave their hands in front of the camera because sometimes they choose to be silly.
"Those virtual AIs, at that time, it was kind of easy mode, because you could do anything in a simulator. You can kind of just say I'm going to go to this location, but in real life there's friction, there's slippage on the floor that makes it so as much as you would try to go there, it doesn't always work out the way you planned."

This gap can catch researchers off guard as they move virtual AI deployments from test environments to physical AI systems.
