I don't get it. What do you mean by "direct brain to computer interface" and why it is supposed to "not be comparable to video"? Our eyes are already integrated as closely as possible with our brain and you can easily feed enough pixels into your eyes to utilize your retinas fully. Why do you think that "direct interface" will be any better? How do you envision input/output with that?

I have a lot of doubt about prophecies of "brain/computer merger" when the message itself isn't clear enough for another brain to understand it. Like, how can the message can possibly be clearer if it's "transmitted" (which implies articulation of some sort) ten or hundred times faster?
