1) No robotics? No interaction with the physical world at all? 2) No measure of the AI's ability to teach others? How can you say AI really understands if it can't then teach 1) what it has learned, and 2) understand what essential facts a tyro does not know or misunderstands? 3) No assessment of the AI's semantic interpretive skills, like those long emphasized by cognitive scientists, such as those in Doug Hofstadter's "Fluid Concepts and Creative Analogies" -- i.e. Miller analogies, double entendres, literary symbolism, poetry interpretation, and so on? Without mastery of analogies, an AI will have all the cultural insightfulness of a portrait of leisuresuit Elvis in neon paint on velvet.
