If I run a simulation of a tornado, and I output the results to a huge screen, from a distance the photons coming from the screen are almost identical in behavior to the photons coming from the tornado. If you want I can even add a pretty sky, a forest in the background. Then the photons coming from a given chunk of the horizon -- where the screen is -- are almost identical in behavior to the photons that would be coming from that chunk of the sky if there were no simulation + screen.
And I don't mean "identical" just to a human observer. They have very similar wavelengths and hence very similar energy, they are aligned in very similar ways, their numbers are very similar, etc. For all practical purposes the simulation has led to a change in the photons bouncing around our world that is very similar to the change that a real tornado makes.
So what do you call that, if it isn't "working?" Even more to the point, what do you call that, if not "existing?"
Saying that something which is producing some actual changes to the world, changes that are very similar to some of those than a tornado would cause, is neither "working" nor "existing" seems absurd to me.
I really want to hear your answer to this because I honestly don't see how your entire argument holds water even in such an easy to imagine scenario. Maybe I am crazy, I dunno.
"Very similar" doesn't cut it.
And do you believe that the display would look similar to a tornado from the point of view of a butterfly?
I doubt it, unless you bothered to set up the output in the spectrum of butterfly optics.
No, the photons coming from that screen are not of the type and arrangement you get from a tornado... they're only good enough to fool the human eye, which is what they're designed to do.
In any case, a tornado isn't defined as the light you'd expect a tornado to emit... a tornado is a tornado.
The simulator is doing what the simulator does, which if you observe the simulator -- especially the part "running the logic" -- is not what a tornado does, which is why it's a simulation and not a replica.
The "tornado" exists only when an observer with the right sort of eyes and ears and brain views the system, and then it exists as a state of the observer's brain.
When the programmer goes home for the night, there's no tornado in the lab, only a machine doing essentially what it would be doing if it were simulating a drag race, or Frodo's journey, or the orbit of Europa.
