There's that word consciousness again which has received a bad rap from the likes of
@Hans Blaster and myself when applied to quantum mechanics.
Since this is a science forum an obvious question which arises is what evidence supports consciousness under functionalism?
In the case for physicalism the philosophical or metaphysical question as to why neural activity produces consciousness science cannot answer but empirically there is a connection between neural activity and consciousness, such as how consciousness is affected due to brain damage, the effect of drugs etc.
For functionalism the scope for evidence is far weaker given that the Simulation Hypothesis shares the same problems with AI, namely how do you test either for consciousness which are non biological systems; it may turn out to be unfalsifiable like the using science to show God exists or does not exist.
Another point that needs to be mentioned simulations are not purely confined to the use of computers.
In my field of having used science in forensic engineering, the simulations are based on the use and development of experiments not computers.
Each shares the same objectives of using model based realities for real world problems but with the use of different tools.
I doubt anyone would consider emerging consciousness from a simulation based on an experiment.
