The simulated wave shows the same imagery as the real one, the wave-propagation looks identical, the optical reflections will be perfectly similar, it might even be possible to predict some wave-behavior.
But the simulation lacks wetness.
The simulation of intelligent behaviour might imitate quite well decision-processes, even the all so human fuzzyness (some might remember the 'humanize'-button on a sequencer of the eighties... a button adding some imperfection to the timing), but no matter how good this form of "Artificial Intelligence" is, it remains a simulation of intelligence. The processes leading to intelligence or artificial intelligence are inherently different. And so mainly the appearances we actively simulate will be found, the simulation still lacks - consciousness
