Hmm, reading this article and noting the reference to the movie Avatar....
Researchers are already using brain-computer interfaces to aid the disabled, treat diseases like Parkinson's and Alzheimer's, and provide therapy for depression and post-traumatic stress disorder. Work is under way on devices that may eventually let you communicate with friends telepathically, give you superhuman hearing and vision or even let you download data directly into your brain, a la "The Matrix."
Researchers are practically giddy over the prospects. "We don't know what the limits are yet," says Melody Moore Jackson, director of Georgia Tech University's BrainLab.
I hate to sound like luddite, but, keep in mind technology is a double edge sword..
-Much of the research focuses on neuroprosthetics, which offer a way for the brain to compensate for injuries and illness.
Not bad you say, but, then there is always this....
DARPA, the Pentagon's technology research division, is currently working on an initiative called "Silent Talk," which would let soldiers on secret missions communicate with their thoughts alone. This stealth component is attractive, but naysayers fear that such soldiers could become manipulated for evil means.
Soldiers manipulated for evil means, imagine the possibilities.
Also, having others read your thoughts....the end of privacy entirely.
I worry about our blind adoration of all these electronics, we may lose our humanity and end up just another machine.
