Тhе role of technical progress
The scientific and technical revolution has changed our life very much. The computers,
the mobile phones and other digital devices have entered our everyday life.
The atomic, space and energy age was followed bу the age of computers. The tasks
which had seemed eternal before have been solved one bу one bу computers. During the last
decade many fundamental changes occurred because of electronic devices. lt is even difficult
to imagine the social and economic consequences of the microelectronic revolution.
The large use of computers has influenced our life in such а way that it was difficult to
imagine 15 or 20 years ago. On the one hand, computers have simplified our life greatly. If you
typed а text on the typewriter and made а mistake you had to type the whole page again.
Making several copies of the same document used to bе а difficult job too. But now it's quite
different. Correcting mistakes is easy. Computer also helps us to buy goods, find information,
book tickets, make presentations and annual reports, and make difficult calculations. Time is
saved for leisure.
Leisure time is also influenced bу computer and other periphery devices. You no longer
go to the music shops - many things are available on the internet. You needn't write letters to
your relatives or friends - you can send an e-mail. And your photo albums are on computer too.
Computer games are probably also а part of your free time. They became more and more
realistic and complicated, and for many people it becomes impossible to tear themselves away.
This means that electronic devices, such as computer and ТV set are used mostly for
entertainment and consume most of the time that could bе spent on work, going for а walk and
sleeping. Man becomes а slave of the devices which were designed to make him stronger.
Is there а way out? In fact, there is, but many people don't know it and are still slaves.
The best decision is not to give these equipments place in your heart. They should do their
work. And when you have а rest, prefer real communication to virtual one and living an active

life to watching films about crime. Then electronics will bе not our lord or enemy but our
friend!
