> if typing speed ever becomes a bottleneck, something has gone horribly wrong somewhere. I've never understood such reasoning. Typing speed is a bottleneck. It cannot be parallelized with other tasks, and therefore, is on the critical path. Improving typing speed will shorten task duration. What is perhaps meant instead is that typing is not worth improving, because gains wouldn't affect overall task duration significantly. But then, why focus on percentage improvement over task duration? I use a keyboard all day. Any improvement affects my day-to-day quality of life for the rest of my life. Keypresses saved, finger, wrist, arm movements eliminated increases my comfort. Removing frictions in work increases flow.
