> could build entire systems at the speed of thought That's kind of of the problem, you;re limited by the speed of though when coding. For most things I can type waaaay faster than I can think (a faster keyboard wouldn't help, just as neural output interface wouldn't help much either), and information can be displayed on a computer screen waaay faster than I can read it (so a higher bandwith neural input interface wouldn't help either). What would truly help would need to be much more complex than that, like something that takes input from something, processes it, then spits the output to other part of the brain, hopefully in a way synced with current visual perception. Or takes input from one part of the brain, processes it through some algorithm, then spits output to another one. My point is that there's a lot to be gained... but I don't think that trivial implementations of BCIs would bring much gain to highly thinking-limited tasks, so the first generation of them would not be of much use to philosophers, software engineers or mathematicians. Probably the first iterations will help most people fighter/drone-pilots or surgeons, who are truly limited by interfaces-bottlenecks, not thinking bottlenecks.
