Every argument that boils down to a claim that X is not "real consciousness" but just an imitation thereof on the basis that "it's just a machine" must explain why the chemistry and physics happening in human brains is not "just a machine".

The only way out is dualism -- that is, to believe that there is something inherently special about the atoms and electrons in human brains. Despite the fact that they are made out of ordinary, non-conscious things we eat and breathe in.
