research is showing that the brain can act independently of the body. One day, you could be sitting in an office and controlling a device from across the room—or in another building. And it’s not just flicking a switch. It could be a nanotool that’s moving through a tiny environment, and you can control it and see what it’s seeing.”

That kind of extension could lead to new spectrums of scale and force, not to mention new kinds of sensory input altogether. Instead of merely imagining that you’re grasping a nanotool with virtual fingers, you could learn to pilot it like a minuscule spaceship—only with your mind. And if that device had any sensors, you might be able to process the data as though it were a tiny camera.

Still, one serious barrier to this kind of technology, is the physical electrodes which must be implanted into the brain. Until brain interface technology goes beyond electrodes, the huge potential of brain machine interface cannot be fully realized.

All those who believe in mind control raise my hand.
