If I'd be judging about functionality, I'd want the headgear now. We have the technology. I read an article the other day on ilovinglovescience and I googled it, plenty of articles from trustworthy sites. A guy in the US was sitting on a chair, in a lab with a helmet reading his brainwaves and a second guy in India in a similar state but had a receptor helmet, interrupting his brain's charges, giving him the same thoughts that the american guy had.
