Despite my bs-filter having toned it down and given me just the facts that it's 3 people in a room with wires on their head playing tetris, with 2 looking at lightbulbs to send signals, it's still got me pumped.
I really believe BCIs be game changers in the way we communicate with electronics (if not other humans), and I for one would love to play a game of tetris over the internet with an unknown mind.
Edit: even in its current transmission rates, I think this tech could have far reaching implications in a better form factor. 1 slow bit is all I need to take a picture, lock/unlock my car, flip the light switch, turn the tap, open/close the door, Start the washing machine, turn the tv on, start the car, close the window, etc.
