The future of cyberspace.
In the last thirty years, the Internet has grown dramatically. In 1983, there were only 200 computers connected to the Internet; now there are around 50 million and this growth is clearly going to continue.

Some experts are pessimistic about the future. One worry is the activities of cybercriminals. Even now, young hackers can get into the computers of banks and governments. In the future, cyberterrorists 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 an explosion of 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 postal service may also disappear with the increasing use of e-mail.

Some specialists see our future in virtual reality - the use of computers with sounds and images that make you feel as if you are in a real situation.
