Artificial intelligence. Conceptual computer artwork of artificial intelligence, showing a printed circuit board (PCB) overlaid with a human brain. Human brains contain billions of nerve cells, interconnected to form a network that has immense processing power. A PCB is a rigid, flat board that holds chips and other electronic components. Computers consist of one or more boards, the principle board being the motherboard. This image could be used to represent the merging of biological and electronic networks into a form of artificial intelligence. In the future, chips containing nerve cells could be implanted in the brain to replace damaged brain tissue, or to augment human faculties.
