“The bionic man brings up some ethical and philosophical questions: Does creating something so humanlike threaten notions of what it means to be human? What amount of body enhancement is acceptable? And is it wrong that only some people have access to these life-extending technologies?
The access issue is especially troublesome, Walker said. “The preservation of life and quality of life has become basically a technical question and an economic question.” ”
“The design and implementation of bionic organs and devices that enhance human capabilities, known as cybernetics, has been an area of increasing scientific interest,” the researchers wrote in the article which appears in the scholarly journal Nano Letters. “This field has the potential to generate customized replacement parts for the human body, or even create organs containing capabilities beyond what human biology ordinarily provides.”
