It’s not been hard to get such information out of the brain, but by having the electrodes ‘in’ the brain it is significantly more accurate and less noisy, plus you can get very fine grained data depending on where the electrodes are inserted. What they’ve pioneered so far is the technology to easily put electrodes ‘in’ the brain cheaply, quickly, and safely, and show that it sends useful data out. The data itself, sure, wasn’t used for much yet, but I know I’d already build a set of things to use such data to perform things for me if I had them. You can build stuff to use the data later, it’s important to be able to get it out very well first. ^.^;
