As a thought experiment that might point you toward why some people say not: if you make an atom-perfect simulation of two 1kg spheres orbiting each other in an empty universe, would that produce any gravitation?
- jtsiskin 7y agoI don’t see how this analogy holds. Gravitation is a physical effect, of course it can’t be produced by software; feelings are not.
- grayed-down 7y agoI don't understand your rebuttal. Feeling are not a physical effect?
- feanaro 7y agoEven though the analogy is not really valid, the answer is probably yes, because simulation (computation) requires energy.
- coffeeiscold 7y agoIf it was well simulated, yes it would produce simulated gravity. Why should there be any expectation that the simulated reality affect the non simulated reality? If you start down that path then you might conclude that no other person has feelings if it doesn't affect you.
- DennisP 7y agoAnd the simulation would produce simulated feelings, but that doesn't mean there would actually be qualia.
- coffeeiscold 7y agoBy "actually" are you again inferring the requirement for cross over between realities? If the simulated brain was experiencing something, then that "something" is an experience in the frame of the simulation. Or perhaps your argument is that, because WE dont identify the simulated brain as a person its experience is irrelevant?
- DennisP 7y agoBy asserting that the simulated brain is "experiencing" something, you're assuming it does have qualia. We actually have no idea how a bunch of atoms interacting create qualia, or even whether they do. There's no math to tell us that a configuration of atoms makes qualia, or what qualia it makes. We have no way of distinguishing between a conscious being who experiences, and a philosophical zombie with the same behavior but no internal experience. Therefore we can't know whether a simulation of atoms actually does capture what's necessary for qualia.
- coffeeiscold 7y agoIf we are going to doubt something that looks and acts like it has qualia, then the same is true for any other human.
- DennisP 7y agoSure, I only really know that I have qualia. It seems reasonable to assume that something which looks like me has qualia like me. But if it's a simulation, it doesn't actually look like me at all. It does have a sort of abstract mapping to something that looks like me, but since I have no idea what produces qualia, I have no way to know whether something essential is lost in that mapping.
