That line of thinking is essentially just solipsism. The only way to move on in knowing anything about the world is to make the methodological assumption that solipsism is false, without demanding proof. Faced with a computer program giving every appearance of self-aware consciousness, a neuroscientist can reasonably make the methodological assumption known as Occam's Razor to assume it is not somehow faking it until there is some evidence that it is. Note that the claim that it might somehow be faking it is not even a well-formed scientific hypothesis, and Chalmers offers no insight into how such a hypothesis might be formed.
