As far as I am concerned , I would say that the modern tools of communication destroy the relations between people because those relations are virtual. Indeed, tchatting through a computer doesn't allow you to meet the persons you talk to . You are behind a computer and talk trhough face book or other means but you don't really have an honnest dialogue with those who are behind. This relation for me is superficial. You can't enjoy it as if you met people and had a drink with them.
But there are situations when some one who is ill or very shy which help people have a social link and therefore no longer feels lonely.
Loneliness is the plague of to day's society and although we live in a modern way and should have more and more friends, it's the contrary because people feel more and more lonely.
