Simulation shows what should happen.
Real-world data shows what actually happens.
Physical AI needs both.
Simulation is useful because it is scalable, repeatable, and controllable.
But deployment introduces friction:
unexpected object placement
lighting variation
human hesitation
motion blur
partial occlusion
surface differences
task shortcuts
environment noise
That is where 𝐬𝐢𝐦-𝐭𝐨-𝐫𝐞𝐚𝐥 𝐯𝐚𝐥𝐢𝐝𝐚𝐭𝐢𝐨𝐧 matters.
The question is not only:
“Did the model work in simulation?”
The better question is:
“Does it still work when real-world conditions change?”
Real-world task datasets help answer that question.
They expose whether a model can handle deployment conditions, not just ideal ones.
