Some experts are pessimistic about the future. One worry is crime in cyberspace. Even now, young hackers can get into the computers of banks and governments. In the future, terrorists may “attack” the world’s computers, cause chaos, and make planes and trains crash.
However, many people are optimistic about the future of the Internet. Already, users can buy books, find out about holiday offers, book tickets, and get all sorts of information from the Internet. “ In the next few years,” says Angela Rossetto of Cyberia magazine, “ It is clear that we are going to see a huge growth in shopping on the Internet.” She also believes that, in the future, we will get entertainment from the Net and that television will probably disappear. The mail service may also disappear with the increasing use of e-mail.
Some experts see our future in virtual reality—the use of computers with sounds and pictures that make you feel as if you are in a real situation. “Personally, I think virtual reality will become a part of modern life,” says Australian expert Peter Anderson.
“I see people living and working in a virtual world. We will work in virtual offices, shop in virtual supermarkets, and we will even study in virtual schools.”
