Human network again

The idea of the human network and its relation to the concept of the human zeitgeist and making of the history/civilization is becoming more and more interesting to me. I might even consider getting some professional instruction regarding the issue. Manipulation of the genetic network by dividing the systems into segments of ready-made codes might change the physical aspect of the being, but manipulation of the human civilization on its full scale by changing certain aspects of the concurrent human network within the civilization would mean creation of directionality in minds of generation after generations of human beings, with some room for error correction and even evolution of sorts.

This idea reminds me of the Hitchhiker's guide to the Galaxy. The Earth was supposed to be a computer for finding out the question to the answer to the life, universe, and everything (the famous 42). Maybe it is possible to design human future on some level by manipulating the human network on large scales, ensuring that certain trait will be passed down and actively sought after by certain segment of the humanity and the human civilization at all times. The repercussion and the magnitude of such program would be enough to call it crafting of destiny, at least as close as we can get to such an act.

I am fully aware that individual characteristics of the complex systems and networks influence the behavior of the whole network/system in unpredictable fashion. Even so, there is a gut feeling that certain traits must be shared equally among systems of similar complexity regardless of its scale and superficial execution. Although I have quite enough to do already, this question, or rather, these questions are just too interesting to pass up... Choices choices.
