I personally have huge concerns regarding man-in-the-middle that is computer. After all, the end goal of such a communication is transfering information from person to person. Having a computer in the middle will lead to such a massive array of problems like tampering with the input, data analysis (this reeks of never before-seen privacy issues), and maybe even mind control. All that simply because there is a programmable interface between two people. I see brain-computer interface only useful as a necessary evil and an intermediary step for brain-brain interface.

Brain to brain interface maybe, I can't imagine brain-computer giving anything but the data we already have (words)
