The creation of the Internet and computers has definitely made a great contribution to science and human activity. Вut of course there are disadvantages. Most people began to imagine life without the Internet and social networks. Most people have had problems with eyesight, posture. Without a computer of course life seems more complicated, it is impossible to learn anything in just a few seconds, but we must not forget that there is a reality where you must use only your mind!
Создание Интернета и компьютеров, безусловно, внесло большой вклад в науку и человеческую деятельность. Но, конечно, есть и недостатки. Большинство людей не могут представить жизнь без Интернета и социальных сетей. У большинства людей появились проблемы со зрением, осанкой. Без компьютера, конечно, жизнь кажется более сложной, невозможно узнать что-либо всего за несколько секунд, но мы не должны забывать, что есть реальность, где вы должны использовать только свой ум!
