 Welcome to Spotlight. I'm Ann Muir. And I'm Liz Wade. Spotlight uses a special English method of broadcasting. It is easier for people to understand, no matter where in the world they live. In August 1998, a silicon chip was put in my arm. This allowed a computer to watch me. My implant used radio waves to communicate with a network of antennas throughout the department. They sent the signals to a computer. It was programmed to respond to my actions. At the main entrance, a voice box said hello when I entered. The computer sensed my movement through the building. It opened the door to my lab for me as I came near to it. It turned on the lights. For the nine days the implant was in place, I performed acts that seemed like magic, simply by walking in a particular direction. Kevin Warwick wrote about this experiment with becoming part machine in Wired magazine. He is a professor of cybernetics at the University of Reading in England. The study of cybernetics looks at controlling systems using technology. Warwick had a silicon chip called an implant. There are many people interested in trying this kind of experiment called body hacking. These people want to change their bodies with technology. But there are many questions about it. Today's spotlight is on body hacking. Humans have been making changes to their bodies for many years. Some people have mechanical implants for medical or health reasons. This technology can help their hearts work regularly or help them to hear. Some people have replaced a missing body part such as an arm or leg with a mechanical one. As technology gets better people can do more. But some people want to go even further. Professor Kevin Warwick says, Since I was a child I have been interested in the study of robots and cyborgs. Now I am in a position where I can actually become one. I believe this desire, this wish to explore, is part of being human. Kevin Warwick became a cyborg when he had a computer implanted or put into his arm. A cyborg is a cybernetic organism. It is a being that is part human and part machine. This sounds like something from a story but it is a part of life for a small group of people. Amal Grafstra helps people add technology to their bodies. Grafstra mainly works with small chips or tags that contain electronically stored information. These are called RFID chips. They are as small as a grain of rice. People use them in many ways. They can be used to open doors or help find things that are lost and in many other ways. Grafstra has implanted RFID chips in himself and in many other people. People changing their bodies with technology call themselves body hackers. Hacking is a way of breaking into something. Body hackers are exploring the relationship between the natural human body and technology. They try to make their bodies do things beyond what humans can usually do. Grafstra told the news organization NPR. Body hackers view the world differently. They believe technology has reached a point where it can improve the human body, instead of just fixing what is broken. A patient may someday very soon come and say, My eye is totally fine, but I want an eye that can see infrared and I want an eye that can zoom. Body hacking takes all kinds of forms. People have put magnets underneath their skin. One man made his finger into a device that connects to computers. This drive stores information. Yet another man attached devices into his head to let him listen to music. Australian artist Professor Sdellark even attached an extra ear to his arm. These are only a few of the ways that humans have tried to use technology to become more than human. Neil Harbison from Spain was born with a problem with his eyes. He cannot see any color except gray. So he had an implant made that plays color for him. He has a camera attached to the back of his head. From this, a long curved antenna hangs in front of his face. It makes sound to let him know what color things are as he sees them. The antenna works so well that Harbison can even see colors that other humans cannot. It is also connected to the internet. Harbison no longer considers himself human at all. He calls himself a cyborg. Harbison created the Cyborg Foundation. This organization educates people about cyborgs. Not everyone is happy about the cyborg movement. There are many difficult ideas to think about. Some people say that it is too dangerous. This is especially true when people implant machines into themselves without a doctor's help. There is a lot that is unknown about body hacking. No one can know what the result of some implants will be. Many people think that the mix of the human body and technology is too risky. Some body hackers have experienced extreme feelings of unexplained fear after getting their implants. And some people simply believe that the human body should remain as it is. They think it is wrong to change the body from its natural state. Richard Wordsworth is an expert in bioethics and bioterrorism. He says that technology is already very easy for people to use. He wonders why people would need to put machines into their bodies. He also asks about what happens when that technology becomes old. If a device is under a person's skin, they will need to have surgery to upgrade it. But Wordsworth also has other concerns about safety. Could technology in our bodies actually make us more open to danger? What happens if someone hacks into a person? They could have a lot of power over a body. WordsworthTalesVice.com I already give huge amounts of personal data over to my network provider. But with my phone, I can unplug if I want to. I can turn off my handset and put it in a drawer. I could not do this as easily if the technology was buried somewhere in my arm. There are still only a few people who practice body hacking. Will body hacking become a larger movement? And is it worth the danger? For Kevin Warwick, the answer is easy. He tells Wired My entire team is working with me to bring humans and technology together in a way that has never been attempted. The excitement of looking into a new world, the world of cyborgs, is worth the risks. The writer of this program was Rina Dam. The producer was Michio Ozaki.
