You see a difference of kind where I see one merely of degree, and your confidence in the sufficient extent of knowledge of nonhuman language and communication, to draw such clear delineations as you do, strikes me as unwarranted. It is a relatively recent innovation in modern understanding even to recognize that any animals beyond our own species have language; where come you by this idea that we know enough about how nonhuman language works to even attempt so broad a conclusion? - or, for that matter, even enough about how human language works? Anyone who's ever tried to explain a complex idea to someone and have them comprehend it, or tried to become a polyglot beyond the age of about ten, should have a better sense of our own limitations than you evince here.
