As Elizabeth Lopatto correctly points out, what's new about this announcement is the way it was announced. "This style of scientific release is unusual; ordinarily, videos like this are supplementary material to peer-reviewed papers published in scientific journals. Those papers contain data that can be checked by other scientists." She provides examples where similar work has been done in the past. In fact, I would refer readers to this comprehensive Wikipedia article on Brain–computer interface (BCI). It points us to the OpenBCI project, which lets people do their own BCI experimentation; software is here on GitHub, though the hardware has a cost. If you have a smartphone, though, you can use audio input as a receiver and lower the cost dramatically. So the future of BCI is easy to predict: open source systems leading the way, followed by commercial ventures that leverage their marketing and connections to create a product line.
