Hi HN, I built FastPlay, a Windows video player focused on the parts of playback people actually notice: fast open, quick first frame, responsive seeking, and simple local playback. A big part of the experience is keyboard-driven control, s

Fair. The title is a bit clickbaity. The more accurate claim is: a lot of CRT choices were constraint-driven (power, heat, phosphor efficiency, flicker, tube life), and those constraints often produced more readable, lower-fatigue defaults
