I would like to point out where I think this can go - neural grafting of cybernetic implants. Essentially creating tactile sensing cybernetic limbs. Why? Because this means that scientists are getting really good at understanding over neural circuitry. From here, we are that much closer to cyberpunk. Scientists and doctors an already wire limbs into the brain so that control is like an actual limb.
side note: This was my intended area of study in Neural Systems at Berkeley and UC-Davis. The Psychology of Cybernetics. And guess what? I can do that with usability/HCI as well.
