> The main advantage of the direct brain-computer interface seems to be speed. But extreme speed is important in only a limited class of circumstances, many of them competitions and zero-sum endeavors, such as sports and games. This statement seems very short-sighted, like the infamous 640k comment. When talking about extreme speed, we’re talking about reducing latency. If I could type this comment with my brain instead of the slow interface that is my thumbs + phone keyboard, that would be a huge win for a seemingly mundane activity, and highly valuable. Writing code would be much faster, for instance. There are plenty of valuable uses for direct brain to computer interface, even simple functions, that don’t involve competition and zero-sum endeavors. It’s like someone saying graphics cards are only useful to gamers.
