With regard to quantum experimental phenomena, might not one think of the movement (light and sound indicators and subsequent recorded data streams) of some piece of macroscopic instrumentation as the results of measurements of the energy of wavelike disturbances within some volume of space during some intervals of time. That is, data streams in quantum experimental setups are generated by the energy imparted from quantum systems to macroscopic instruments. The Born rule says that the probability of a quantum system to produce a changes in macroscopic instrumentation is directly proportional to the square of the amplitude of the quantum system. With respect to classical systems, the energy transported by a wave (and imparted to obstacles in the wave's path) is approximately equal to the square of the amplitude of the wave. Is this where the Born rule came from?
