Cyborgs are no longer just characters in science fiction movies. They live among us. Technology has developed to make life easier, but is there a bad side? Some humans have implanted devices in their skull to sharpen their senses and become cyborgs. Others have planted magnets in their fingers, or chips underneath their skin to open doors.

He is color-blind and can only perceive the world in shades of grey. However, the "Eyeborg,” an antenna in his head, allows him to hear colors. A sensor scans the colors in Neil's field of vision and then a chip in his head converts them into sounds. Each color has its own individual sound in his ears. Not only can Neil cannot hear the spectrum of colors visible to us, he can also perceive ultraviolet and infrared waves. Neil Harbisson is a co-founder of the Cyborg Foundation - an international organization that helps people become cyborgs. But at what price - and where are the limits? Are we losing our humanity? What would happen to society if some people had superhuman abilities? Whatever the answer, technology is already getting closer to us than we could ever have imagined - in some cases even under our
