I read something the other day that said we were almost at the point where people could control things by thinking of them. For instance, you place a device on your head and it reads your brainwaves/electronic pulses and when you think “play music” it could translate that and actually tell a media device to play.
Now take that a step (more like jog) forward and why couldn’t we develop a device that can read someone’s thoughts from a distance? At first this would likely be pictures or interpretations of pictures and sounds based on patterns the devices detect. This would likely be accomplished with the use of some sort of directed laser (love lasers :) ). Actually the first prototypes would probably need more than one laser triangulated on target. Future versions would be able to do the same thing using some sort of spread spectrum thing based on cranial shape, size, etc. If you combined the laser aspect with say maybe inverse sound waves you might get a better resolution of picture/sound?
Imagine the implications this would have on human intelligence gathering (HUMINT) by a country’s intelligence apparatus. Actually kind of scary if you think about it. Maybe this is one of those things that shouldn’t be.
Then again what an amazing tool for law enforcement. Instead of hooking a suspect up to a stupid lie detector machine (archaic and ancient) they could just sit them in a special room, ask them questions and see what the person remembers of the incident. Not only could they ascertain someone’s guilt or innocence but they could also pull that one piece of critical information from a witness, say a license plate that the witness didn’t even remember seeing.
The worst part is once this is a reality, someone will ultimately figure out how to reverse the damned thing and push pictures, sound (false memories) out to people rather than collecting it. Bad thing.
