Telekinesis and telepathy are here. Check out the video (link - not the video embedded above) of the monkey getting food by controlling a robotic arm with only its thoughts. DARPA’s 2010 budget includes a line item for the Silent Talk project, which “will allow user-to-user communication on the battlefield without the use of vocalized speech through analysis of neural signals. The brain generates word-specific signals prior to sending electrical impulses to the vocal cords. These signals of “intended speech” will be analyzed and translated into distinct words, allowing covert person-to-person communication.” Basically, DARPA’s talking telepathic soldiers. Scientific American jouralist Christie Nicholson brought up both examples in her presentation "Is the Brain the Ultimate Computer Interface?"
Nicholson’s presentation may raise ethical issues that the vast majority of the world’s population remains unaware of. In the last few years, she reports, the rate of progress in working brain-computer interfaces has been exponential. The latest generation of brain to computer interfaces includes planting electrodes with growth hormone into the brain so that neurons begin to accept them as part of the living flesh. A computer chip was developed and successfully replaced a rat’s hippocampus – allowing researchers to directly upload “instructions” that were translated into physical commands much like the rat’s original hippocampus would. Optogenetics is a relatively new science that allows researchers to control a mouse’s brain through light via a light receptor implant.
All this is possible because 1) the brain is electric and 2) the brain is plastic. Electric impulses can be translated into complex algorithms and modified. Neurons can rewire themselves based on need – e.g., if the visual cortex is damaged, the aural part of the brain can rewire itself to compensate.
Challenges remain to creating a direct port into the brain for uploading instructions ala Neo learning kung fu in The Matrix. Much of thought is contextually relevant and temporally variable, so creating a “genome project for the brain,” decoding all its functions and translating into an algorithm may be quite complex. However, it was not long ago when the Genome Project seemed impossible until a leap of insight changed that reality. We already have devices on the market that control games via thoughts. Mindscape by Mattel is one. It doesn’t take much to imagine the trajectory from a EEG headset device like Mindscape’s toward increased comfort with more direct user interfaces between technology and biology. Quadriplegic Matt Nagle is an early example of this potential with his use of the BrainGate technology
Under these scenarios, the individual would either have to consent or be coerced to adopt brain-computer interface technology. Still, as a marketer myself, I am fully aware of the power of marketing as a coercive force. When presented with the upside of telepathy, it’s an open question whether the downside implications will be addressed or ignored.
