What is this passage about?

Many computer enthusiasts predict that, in the future, everyone will use computers for almost every- thing. We will no longer have to go outside to shop because we will be able to buy everything over the Internet. There will be no need for paper books because we will be able to order any title we want from an electronic bookstore. We will be able to use the Internet to book our holidays, rent films and order pizzas. However, while some people might feel excited at the thought of being able to do so many things from their homes, others argue that computers will never replace the old-fashioned methods of shopping.
