There are 2 reasons why..actually there are 3..or well really there are 4 reasons why all keyboards should use braille dots. The first and most important is for my convenience. If my keyboard was written in braille, presumably I would always know which key my finger was on. The dots on f and j help but not if I am playing a video game, which we can all agree, is extremely important. Second, it would be a pretty useful tool for learning how to type, something I still don’t do all that well (lot’s of speed, not a lot of accuracy). Third, blind folks might kinda sorta appreciate being able to use any and all keyboards. And lastly, we would all know how to read braille.
The only possible downsides to this is the unknown potential for finger irritation due to repetitive minor abrasion, and the somewhat insignificant retooling costs of keyboard manufacturers(they have to retool rather regularly anyway)
