Peter Taylor finds out how computers and the Internet are going to affect our lives. In the last thirty years, the Internet has grown rapidly. In 1983,there were only 200 computers connected to the Interent;now there are around 50 million and this growth is clearly going to continue. 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.
