I thought of responding to that bit too, changed my mind, but your response made me reconsider again. The response is simple, just a quote from Yudkowsky: "The AI does not hate you, nor does it love you, but you are made out of atoms which it can use for something else." When all one knows about potential future AIs comes from sci-fi, and the only sci-fi one reads or watches is weak sci-fi with very human good/evil AIs, one's frame of reference in the discussion about whether concerns are warranted or not is way too narrow to be worth any further consideration.
