Have you ever watched the movie Enemy of the State? There's a line in that movie I can still remember that went "The only privacy that's left is the inside of your head. Maybe that's enough."
Well, so much for that idea. Science Daily reports that neuroengineers at Columbia University "have created a system that translates thought into intelligible, recognizable speech. By monitoring someone's brain activity, the technology can reconstruct the words a person hears with unprecedented clarity."
What could possibly go wrong?
