Does it matter if "intelligence and reasoning" are there if what they produce is indistinguishable (or outmatches) what a human could produce?

You only have your own experience to judge that you are even reasoning. You assume others have similar experience and so reason like you because they are able to do all the things that you do - and they look human like you. We can't prove there's a there there in other humans. What happens when the robots are doing everything humans do? What happens when they tell us they are reasoning, when they say they have an internal experience? Maybe there's nothing there, but you can't prove it. Moreover, it's likely they'll be able to affect the world and you in most of the same ways as humans can, whether there's a there there or not.
