Why is everything on-line?

Today everything can be done on-line. Most of my mail is on-line. You can order anything you can think of just by doing a casual search and it will be delivered to you in as short of period of time as you want it to be. The internet has really taken over our society. The world as we know it is now wireless. The more technology we create, the more we rely on it. The internet is a wonderful tool, but we use it for everything. Our homework for classes is even on-line now. In subjects like calculus and chemistry it just seems like an excuse for our teachers not to teach or grade any work. The students have to become their own teachers. You can find anything now on the internet. Some people just stay at home and run their own on-line business for a living. It all just seems too impersonal. Why do we flock to the internet for our every need? Need a map? Internet. Looking for textbooks? Internet. Want to know how your friend is doing? Internet. Why? Because we can?
