We are all Cyborgs
The arrival of the cyborg is made possible by the gradual removal of the barrier separating exteriority and interiority, as well as public and private space. This collapse of differences proceeds in two directions at once: from outer to inner and, conversely, from inner to outer. On the one hand, the body is progressively colonized by prosthetic devices. Implants, transplants, artificial organs, artificial insemination, genetic engineering, and synthetic drugs make it harder and harder to be sure where the so-called human ends and the non-human begins. On the other hand, artificial wombs, test-tube babies, artificial intelligence and computer literacy "externalize" bodily and mental functions to such an extent that the outer is not more merely outer and the inner is not simply inner. No longer purely human, we are not yet replicants.
In the age of cyborgs, do people evolve into machines or do machines evolve into people? Where is the person/machine line to be drawn? Indeed, is it any longer possible to draw such a line?
Electronic media are supplements to the human organism. Computers become the brains, engines the legs, video cameras the eyes, telephones the ears, and wires the nerves, veins and arteries of the world organism. The lifeblood of this corporate body is electricity. When the blood flows, the globe becomes a cyborg.
