The term Thinking Machines referred to both actual beings and a general concept, both of which had a profound impact on the development of humanity over the span of many millennia.
Thinking Machines’ Empire
Basic Machines and the Cymeks
Omnius and the Metal Based Thinking Machines
Conceptual Thinking Machines
Following the rise of the actual thinking machines, and the physical and psychological damage they inflicted on the free humans, the very concept of a sentient machine became abhorrent to humanity.
Animosity against seemingly intelligent machines often escalated into outright hysteria, and resulted in a widespread hatred of mechanical objects. This hatred lasted through the ages thanks to rigid cultural restrictions, a good example of which was the Orange Catholic Bible's supreme commandment: Thou shalt not make a machine in the likeness of a human mind.
Unity with Man-Kind
Although Thinking Machines continued to be mankind's greatest enemy in the span of over fifteen thousand years, they eventually did achieve an understanding and a type of unity with the rise of the Ultimate Kwisatz Haderach, Duncan Idaho.
Idaho was able to merge with and accept the Evermind controls from the Erasmus before Erasmus died, which enabled him to direct the entire Thinking Machine Empire during the time of the Kralizec, and for hundreds of years afterwards.
