Today people more than ever are overwhelmed by worry about current events. Why are some people devoured by hatred and bigotry? Can we avoid the next economic crisis? Can we prevent the next global war? Will computers take over our civilization any time soon? Even though Vertical Progress does not have all answers, it provides readers with plenty of new ideas to open the debate. Vertical Progress offers a hypothesis and rationale that provides not only a different look at past events but also explains much of what is happening now. The book sees the human society as a well-designed, complex information system that has a single purpose—to build a collective knowledge. Using results of the computer simulations author demonstrating that as just a heard of collaborative individuals, the society would not be able to make any substantial progress. The book logically connects the latest achievements of science with the findings of the computer simulation experiment to lead readers to the inevitable conclusion—the social information system would not make any progress unless it operates with more than one type of nodes. Hence, the author suggests that our civilization consists of more than one human kind.
