Bionics, the first generation of truly integrated implants, was introduced as a means of repairing or enhancing human body with inorganic materials on a microscopic level. Such microstructures allowed excellent and seamless transfer of both information and energy between the natural and artificial parts, making limb, eye, or spine replacement not only possible, but pretty cheap. Such was the efficiency of such systems that certain military organisations actually encouraged implanting bionic parts, since they were generally more resilient and stronger than original parts, and could be replaced easily. Even the street followed the trend: bionics became popular with street gangs and extreme artists.
