With the statistics that are given in the text, I will agree.
Firstly, in our time the Internet has a huge demand and young people aged 16 to 24 prefer the Internet in quality. Example: the source of information, communication with friends and recreation (games, movies, etc.).
I know for myself.
Secondly, the text spoke about security and personal information. A person shares and leaves information about himself without fear, not everyone reads license agreements and a statement of confidentiality. We strongly believe in the security of the Internet, why would anyone hack into our mail or an account on facebook, so people often use the same passwords and are very risky!

In conclusion, I would like to remind you that the Internet is a whole universe that will never die and will develop and improve. Of course, the Internet has made our life faster and easier, but do not forget about its black side.
