Technology is really used in the story so that you can see how they use surveillance and control from technology because while in the story it says that Mr. Meads said he heard a metallic voice speak to him. Which can tell you that it had to do anything because someone is always watching you. In the text is says that ¨A metallic voice called to him:"Stand still. Stay where you are! Don't move!" He halted. "Put up your hands!" "But-" he said. "Your hands up! Or we'll Shoot!" This evidence shows you that with having technology doing everything they are on watch all the time and they dont stop watching until they catch you doing something they wouldn't like.
