Neuroscience is one of the most rapidly advancing fields in medicine, with highly-detailed imaging offering new insights into the way the brain works and direct brain interfaces enabling weapons to be targeted and fired with just a thought. The technology is not speculative - just last week scientists unveiled an implant called BrainGate that enabled a woman who had lost the use of her limbs after a devastating stroke to control a robot arm using thought processes alone.
Technologies such as the BrainGate implant have already shown that machinery can be controlled with the mind alone, and games manufacturers have already brought out low-cost helmet controllers than enable wearers to play by mind power alone. The obvious application for the military is mind-controlled weaponry and remotely-piloted aircraft, which could make operation and reactions far faster.

So what else is out there? fMRI technology makes for infallible lie-detector machines for interrogation purposes. Electronic surveillance is already the norm...
Orwell's 1984, may not have been pessimistic enough... Welcome, to the Machine!
