Communication

Centuries ago the humans need to contact with other people who lived far away from each other, and taking a journey, it was bit dangerous and expensive. So they started sending letters, and this was a good idea, without going outside you could write a simple letter to your friend to ask how's he going, or ask for some information. Nowadays we don't use much this idea of sending letters, instead of this, we call to our fried by phone, or write to him by e-mail or write to him at instant message program. What will happen in the future, will the communication change to a new one and be the best of all? Will this change our lives? What we know is that, we will be able to speak with all the people arround the world whenever we want.
