The US will need 70 percent more home aide jobs by 2020, long before that bubble of retirees. And while filling those jobs is proving to be difficult because the salaries are low, in many states, $20,820 annually. Researchers at the Georgia Institute of Technology have developed Cody, a robotic nurse the university says is “gentle enough to bathe elderly patients.”  http://bits.blogs.nytimes.com/2013/05/19/disruptions-helper-robots-are-steered-tentatively-to-elder-care/  Hector, a robot that is being developed by the University of Reading in England, can remind patients to take their medicine, keep track of their eyeglasses and assist in the event of a fall. “Giving old people robots to talk to is a dystopian view that is being classified as utopian.” Robots did not have a capacity to listen or understand something personal, and tricking patients to think they can is unethical. It is about making something that is not human still appear, somehow, trustworthy.
