Problem 5: I think people have already become tools of tools. Take my personal experience. I usually spent almost most my day on computers. Computers have already dominated my life. I can no longer live in a life without computers or smartphones. And especially for social networking media, like Facebook, most teenagers are so dependent on it. However, these Social Media blocks your real networking in your life. Also, people spent lots of time and money on computers. It costs us too much, not only money and time, but also our real lives to live i in a world with computers everywhere.
Problem 8: I think websites should use cookie only if it is under user's knowledges. Cookie is like a two edges' weapon. In one hand, it can help the website to guess their users' habits, in order to provide better service. However, if cookie is used too much, user's privacy will be violated. Thus, cookie have to be used carefully and under the full knowledges of users.
