namaste Yamaka.
I was thinking specifically about this implication:
If the brain can be made to communicate with the computer so the brain waves can be digitally read, then it should be possible to read a person's thoughts. And if this communication could eventually be made duplex, then the person can be brainwashed! If this technology matures into use of tiny wireless devises like those we see in a TV serial such as '24' or 'White Collar', many practising people will have a field day, the Hindu astrologers among them!
The mind (brain in your parlance) can not only be controlled, but nourished, so autistic children could reap the benefits. Scientific studies into the spirituality of a person could become more and more credible, uniform and authentic. Eventually the entire human nervous system can be brought under control, and that, coupled with the researches in DNA for tissue replacement, could rejuvenate a person. And then there will be the inevitable wrong uses of the technology...
