Mcluhan compares our lives in the digital era to an electric circuit in the way we handle and process new information. Mcluhan believes that we retain no old information when new information comes our way. He believes that the old info leaves us because we have to make so much space for the constantly new, incoming info that we need to process. He makes an example on page 63 about only retaining enough information the pass the test that is most recent, but you will have naturally forgotten the info of the past exams so that you can make room for the new info. I believe that this is true for some individuals who don’t make an effort to retain the previous information that they learned. There are some people that only retain just enough to pass their exams, but that is because they don’t want to remember the old info.
