How about cheap brain implants for a virtual reality? You wouldn't even have to use many resources and you can unplug the masses from feedings over time.
Why not just mind control? Ever heard of
Jose Delgado? Dark Matters: Twisted But True show did a part on him "
Remote Control Man". It showed through electrodes in the brain he could induce deep thought or emotion like anger or even sexual arousal. There is one part where he turns the switch on and the subjects hand was clenched. He asked him to open his hand. His response was "Doctor your electricity is stronger than my will". He later developed a wireless version called a stimoceiver but was quite clunky at first. Later revisions had it down to a silver dollar size and this was early 70's!
He then decided to go bullfighting with a steer implanted with one of these stemoceivers. The results were
satisfying to say the least. He proved that an electrical impulse could stop the aggression of a charging bull.
Below that video is a quote from one of his books.
"We need a programme of psychosurgery for political control of our society. The purpose is physical control of the mind. Everyone who deviates from the given norm can be surgically mutilated. The individual may think that the most important reality is his own existence, but this is only his personal point of view. This lacks historical perspective. Man does not have the right to develop his own mind. This kind of liberal orientation has great appeal. We must electrically control the brain. Some day armies and generals will be controlled by electric stimulation of the brain."
So I ask you. Knowing how long ago that was and taking into account the massive changes in technology, what does a "stemoceiver" look like today? Once a mind is mapped to know where each emotion and which part moves limbs, how long before you can play master of puppets?
