"It’s the old trope, echoed by Philip K. Dick for one"; I always felt that Jack Vance got short shrift on this. In the ~1958 "Languages of Pao" he had body augmentation as a major subplot: "... The anti-gravity mesh was laid into the bottom of the feet and connect to the processors in the calves by means of flexible tubes thrust up from the feet ... a switch was installed under the skin of the left thigh..." Almost certainly the all too brief "Technomages" of Babylon-5 were based on these Vance characters.
