Let's not get over dramatic here. To sound natural of course the computer system has to copy natural behavior, which includes manners. The experimental version of this system happens to include behavior modeling of phone conversations of people that live where the developers work and live, seems logical. It doesn't mean that the same model will be used in other cultural contexts. An ideal model would copy your behavior (and/or voice), so it would be like you calling. Just have to let Google listen and analyze all your conversations :)
