This probably needs more explanation. You could tell that my reaction is not in appropriate place. It is probably true. BCI we could define like physicaly interconnection between brain and computer.

But I think in this moment we could (and have) analyse also trained "horses" with trained "raiders". And also trained "pairs" (or groups?)

Better interface between computer and human could be done also in nonivasive path = better visual+sound+touch interface. (hourse-human analogy)

So yes = I expect they could be substantially useful also in case that direct physical interace would too difficult in next decade(s).
