New cyber prostheses are already directly connected to the nerves.
Only recently, two or three years ago, imagination was struck by prosthetic hands, which, in fact, were not so many and were able to - just twist the wrist, and flex the fingers, and according to the preset patterns that the person chose himself, cutting the muscles in his hand in order to transmit prosthetic team. In fact, this hand allowed you to return some of the functionality, but still remained a prosthesis , trying to imitate lost abilities. But now everything has changed.
Mr. Le Bow, who lost both hands as a result of an incident, equipped cyber-limbs with the full degree of freedom of an ordinary hand, which are controlled directly by thought.
Despite the fact that while the host of a limb can control it in mono-canal mode, it needs to build up the arm position behind the hinge - I am still inclined to say that this is the first full-fledged cyber limb, and not a prosthesis. The problem with limited control will probably be solved in the future; the first home PCs also did not have gigabytes of memory.
