The story of the Tower of Babel should be understood as a story about the foolishness of attempting to achieve metaphysical elevation by physical means.
Transhumanism is another Tower of Babel. Technology cannot grant transcendence.
Becoming superhuman, becoming shaman, is a process of subtraction not addition. It is an ordeal. To become spirit, the prospective shaman must first experience death. Only then can he visit the heavens and the underworld. Cyborgs cannot do this.
