constantly tracking your eye movements to create a map of what you like is a huge step beyond what we currently share with Google and co. They’d know things about us we don’t even know! It would be like letting Google peer through your webcam to work out when your getting bored online and react accordingly, a step too far that no-one would put up with. People won’t be jumping at the chance to pay hundreds of dollars for the privilege of Google sucking unconscious brain data out of their eye-sockets, so there’s no way this one’s gonna happen.
