How Science Can Give It To You:
The Brain-Gate Neural Interface System (BGNIS).
Foxborough, Massachusetts based company Cyberkinetics Neurotechnology Systems, Inc. is working on technologies that let the paralyzed interact with their surroundings using only their thoughts. The "Gate" in the name refers to a computer interface that acts as a gateway for the entire process. The system begins with the implantation of a sensor in the motor cortex, the part of the brain that controls movement.
This sensor detects neural signals that your brain would normally use to tell your body to move. But, rather than having this information transmitted to an arm or leg these signals get relayed to a computer which then decodes the information and converts it into a physical action. So when you think about an action (say, giving a stripper a dollar) that thought would go though the computer which then would activate a device (say, the dollar bill cannon attached to your pelvis).
The BGNIS project has been approved by the FDA and Cyberkinetics hopes this technology will be ready for the mass market within three to five years.
The only problem is ...
This technology clearly isn't going to stay limited to the disabled. The prospect for being able to, with a simple implant, turn on your coffee maker or car with the power of your thoughts, will be too much to resist. How will a society already plagued by obesity and sedentary lifestyles adjust to the invention of the mind controlled pudding cannon?
And how long until a group of rogues find a way to get souped-up implants that let them take over your car from a mile away? Or send your lawnmower on a murderous rampage?
They'll also make it fly somehow
Without the wisdom of a Dr. X to guide them, they will wreak havoc on a world too fat to defend itself.
