It’s likely the world in the not-so-distant future will be increasingly populated by computerized people like Amal Graafstra. The 37-year-old doesn’t need a key or password to get into his car, home or computer. He’s programmed them to unlock at the mere wave of his hands, which are implanted with radio frequency identification tags. The rice-size gadgets work so well, the Seattle resident says, he’s sold similar ones to more than 500 customers through his company Dangerous Things.
The move to outfit people with electronic devices that can be swallowed, implanted in their bodies or attached to their skin via “smart tattoos” could revolutionize health care and change the way people interact with devices and one another. Critics call the trend intrusive, even sacrilegious.
But others say it ultimately will make life better for everybody. Some researchers and executives envision a day when devices placed in people will enable them to control computers, prosthetic devices and many other things solely with their thoughts.
