This was in response to your comment about how you can tell that a water simulation is fake by trying to dip a water bottle in there. The distinction between chemical and silicon doesn't matter when the output is text. There's no physical test you can perform in the text, like dipping a water bottle in water, to see if it's chemical or silicon.
If you test both on the same terms (i.e. only interaction via a remote terminal) then a decent simulation can entirely convince humans that a bottle has been dipped in it and water removed from it too. But it still doesn't have the essential properties of H20, it just looks like it in many ways to some imperfect observers.
Testing is a moot point when my original argument was that it there is no reason to assume that a converts-to-ASCII subset of i/o as it is perceived by a [remote] human observer other is the only differences between two dissimilar physical processes (one of which we know results in sensory experiences, self awareness etc). Takes a lot more belief that the human mind is special to believe that sensory experience etc resides not in physics but whether human observation deduces the entity has sensory experience.
