Sure. The problem is this video somewhat misses how that interaction actually works. You need a control technique of thinking to action. What that actually is and how you learn to use that is missing from the demos. Thats a tad misleading right now IMHO.. (NB: It could be intentional speech eg "Move x to y" or it could be intentional motor control "move my hand right and up" You would also need a stop command. Not sure.. )

But sure - "the potential" is the key thing in all this. Just the cost to benefit ratio is pretty dramatic right now.
