A person begins augmenting themselves with cybernetics despite the fears of cyberpsychosis. The person seems remarkably unaffected. After a while they begin to find new augments that they don't recall putting in there. As the story progresses it gets increasingly uncertain whether it's the person acting, or the augments. (Perhaps in the end there are only augments left, and yhe person is gone completely, thus fulfilling the person's fears of cyberpsychosis death). Maybe it's a plot by a new corporation that needs lots of robots but can't afford them, so they make people pay for their augments that end up completely destroying anyone who uses them, turning them into bots.
