The only sane reason that AirBnb or Uber are worth as much is that they promise to be more efficient than traditional companies. SO the 'market' pays for efficiently and a lot of digital revolution has been all about making existing processes slightly more efficient (Amazon online shopping experience vs physically going to the different shops etc) So the market definitely value the efficiency where the cost of developing that efficiency does not outweigh the benefits. Typing speed and cursor refresh are not limiting factors for programmers so there's diminishing return in making text editors refresh >120hz. Simple business logic and OP can lament as much as he wants to but we have limited resources, mostly time and that time is usually better spent writing business logic than optimising text editor for the 100th time.
