A biotechnocratic society controlled by a synthetic intelligent organism. Everyone is modified to have biomechanical chips in their nervous system core/brain. The State Intelligence monitors thoughts, actions, considerations - both conscious, subconscious, and unconscious. And then it changes things as needed to bring about an outcome as desired by the State Intelligence.
The State Intelligence's mind and definition of 'optimal' outcome would be based upon every single right-wing dictator ever. The State Intelligence would be left to its own devices to eliminate contradictions.
Everything would end perfectly fine as every facet of society, including individuals, is regulated by the State Intelligence. Even the process of birth and reproduction, and who does what with whom. Presumably, if eugenics is utilized at all - then the State Intelligence could optimize such a thing to the point that there would be minimal inbreeding and yet maximum capability for a single ethnicity to win out above all others.
