What is a non-theist argument that dictates we should treat synthetic “consciousness” as fundamentally different than biologically derived conciousness? I think this is a valid question Even if the strongest evidence for machines having “real”consciousness is its external/utility indistinguishability from biological consciousness ? It would seem to me that a machine that seems to be conscious and professes that it is should then be treated as if it were, if for no other reason than the likely outcome of not doing so - creating “synthetic distrust and enemity” between “conscious” machines and humanity. It seems like if we are going to ignore the “utility” argument for consciousness, we then must prove that other humans as well are actually conscious, and not just appearing to be so. Seems like a bad place for the species to go, for a multitude of reasons.
