Seeing red

I cant rule it out.  They would diverge from, -at least- the very moment of their cloning (this assumes process perfection).  You'd have to test them awfully quick.   This, though, isn't the part that I had hoped to comment upon...rather, why we would go from an unexpected result in such a test (that, for example, two identical "consciousness systems" had divergent perceptions) to: 

"a personal god"

or

"there must be some other type of stuff".


Neither follows.  Nor would such a result eliminate all previous results in which the brains involvement in experience is made demonstrably clear.  That would all still be there.  This is, essentially, the old "evolution is false..therefore goddidit" bait and switch.

I don't know how you've got to this, thinking that I'm trying to 'bait and switch' you First of all you can cross off "a personal god" from the above because I would not even hazard that as a possible alternative. But the second one, yes, if I could not even rely on the assumption that system X produces conscious state X... that system X in exactly the same state could produce two different perceptional states, then I would, myself, have to start thinking about other alternatives and probably give up on even trying to understand the brain and would probably end up going in Bennyboy's direction, of idealism.
