Computer Human Evolution Facts

Today another brilliant idea came down to me. It’s about the influence of scientific and technical revolution on the evolution of human society.
It seems to me it’s an interesting observation: how human society with help of Internet step-by-step globalizes into a one big community.
To illustrate this idea I offer you to look at the history of human society from the very beginning of it’s existence. At first, all people were united into one bug tribe. But then it has grown so much that there were problems with management – first people had only primitive understanding of management. That was in my mind the main reason that cased them to divide into smaller and smaller communities.
The later history of human shows the improving of management tools and that human communities tend to unite.
Countries try to participate in different blocks an unions, but it’s on a political and economical level.
As for social level – human communities become bigger and more tight. It’s a very huge and powerful machine – human online communities. I don’t think someone will argue that it is possible to find ways of managing and psychologically affect these communities. This is the great power.
I wonder who found this… Who prepares this great power for himself? For what reasons and purposes? I think the next revolution will be computer-based and worldwide-spread.
