At some point these machines will start wondering whether we humans are really like them or not. They might propose a ‘reverse Turing test’ to see whether we are intelligent, but we would certainly fail that. More relevant here, they might try to invent a ‘reverse Turing test’ to find out whether we are conscious. They would no doubt confront all the familiar problems of subjectivity and other minds. But by the time this happened we would probably already be treating them as conscious beings like ourselves, whether or not we have resolved the problems of consciousness.
Funny is to think about future times where there will be robots among us and they will wonder "Is the humans really what they think they are!?". And they themselves will purpose their own test. I think it's a test that will answer if humans are robots or not.
The Ethology father, Konrad Lorenz, proposed once as the postulates that founded this science, one that says "any species treats others like belonged to its own species". Dogs, by its instincts, "think" that we are "dogs". Parrots think that we humans are "parrots", too, and behave accordingly with that.
Even we humans think and treat other species individuals that they were humans too. We don't see people "talking" with their pets, as those pets belonged to their brethren ? We, humans, after all, are no different than other species. This "extended Turing test", as we can call it, could be seen as a way a species could determine if another individual could belong to their species or not. When we are talking about individuals, I'm not distinguishing if they are biological (or carbon-based) or not so (silicon-based). I'm starting from the point of view that states that any lifeform, independently of their chemical basis, can reproduce itself.
