We implement zero-tolerance policies in our schools and businesses. We improve on the atomic clock with the quantum-logic clock that is twice as precise. We use multi-angle instant replay cameras in certain professional sporting contests to make sure the referees' calls are flawless. We spend millions on plastic surgery. We strive for higher fidelity, resolution, definition, everything.
