In future, it will be possible to think of the body as a building set that can be redesigned or expanded as required. While pacemakers and artificial limbs are now established aids for compensating for physical disabilities, new technologies are being deliberately used to break down natural barriers. So-called wetware, i.e. implanted electronics, is capable of controlling complex processes in the body biocybernetically. Micro-chips under the skin can collect and store many kinds of data. Other applications can be fitted to the exterior of the body, such as strengthening exoskeletons. Ambitious targets like extending the human lifespan or even attaining immortality can also be taken into consideration.
