We won't consider machines intelligent until they have and demonstrate the capacity to consider us not-intelligent. I can't see how this claim is even slightly illuminating aside from it's pure "quip-ness". A robot playing, say, the game of go, might spit-out "you are not intelligent" whenever it wins. Is that "the capacity to consider us not-intelligent"? You could even set-up a micro-world where virtual entities interact, evolve and rate their opponent. It wouldn't be hard for these entities to compete with humans in this arena, to do better than humans and so to give human poor poor evaluations but the entities to be pretty simplistic and far from what humans consider intelligent and far from fit outside the micro-world (you could do it with adaptive game-theory solvers, say).
