"The first person generated a series of zeros and ones, where they imagined moving their left arm for zero and right arm for one." The first time I heard that people could operate robotic limbs with their thoughts, I thought: Two people could communicate almost telepathically, if they'd just hook up this brain reader to a Morse code transmitter/receiver. Ultimately, this could lead to a little device that sits behind your ear, allowing communication from person to person, completely clandestinely. On the sending end, perhaps you just have to think about moving your fingers to type, and it picks up the letters from your brain waves. On the receiving end, it uses text-to-speech to read the message back into your ear.
