But as a practicality, with eyephones, datagloves, bodysuits and feedback loops, entering a world of computer-generated simulations of everything from a "smart" bomber to a protein molecule, from cadavers (virtual surgery) to solar systems (virtual astronomy), VR is still at a clumsy holographic stage, with here and there some "telepresence" (seeing things from a robot's point of view), but yet to cross the "vibrotactile" threshold, not even up to the primitive standards of Gibson's "simstims," and nowhere near the great wet dream of "
teledildonics" (virtual sex).
