Panpsychism is also, at this point, just a placeholder for anything resembling an explanation, and it is not necessary for dispelling the notion that humans are unique (in fact, it is quite plausible that other (now extinct) hominids also had self-aware, theory-of-mind-holding, language-using consciousness.)

As to whether there is something special about it, I personally feel that the difficulty of explaining it is enough to regard it as such.
