So maybe your natural thought process wouldn't work for said use case, but like keyboards and other user interfaces, you could surely learn to control it fairly simply. Maybe it's as simple as training yourself to imagine the words spelled out (if that was all it took). We've all seen people who are new to keyboards, mice and even GUI's attempt to navigate a computer. It's clunky, slow, there's a lot of noise in the movements and erred clicks made. I think it was here on HN I saw a great write-up once about leaving the gap in UX—that there is a threshold where the use just simply has to learn something in order to effectively use the device. I don't know how the control interface for thought could look in the end in so few words, but I'm reasonably confident it could be brought down to a certain level that is more than attainable for the average user to meet.
