> I think people just have very different tolerances for latency and slowness.
I wonder if it's because of a form of "touch typing". I'm not really looking at text appearing as I type. My fingers work off an internal buffer while my mind is planning the next problem. If not so deep in thought to almost be blind, I am reading other docs / code as I type. I am not an ultra fast typist but if I mistype, I can feel it and don't need the visual feedback to know it. I might be this way because I am old and have used tools with lag you measure in seconds.
I only care about latency if it interrupts me and I have to wait and that's typically not typing but heavier operations. I am utterly intolerant to animations. I don't want less I want zero, instant action. I don't want janky ass "smooth scrolling" I want crisp instant scrolling. I have no idea why animations are even popular.
Some of the text-editor latency discussion reminds me of high screen refresh rates for office work. When people "check the refresh rate" they have to do that violent wiggling of window to actually have large content moving faster enough to see a difference. You have to look for it to then get upset about it.
The worse case would be if it's more of an illusion like fancy wines - a fiction driven by context. Lie to someone that an editor is an electron app and they will complain about the latency. Software judgement also has toxic fashion and tribal aspects. Something unfashionable will accrue unjustified complaints and something cool or "on your team" will be defended from them. I'm reminded of Apple fans making all sorts of claims about rendering unaware that they were using Apple laptops that shipped not running at their natural resolution and visibly blurry. Your lying eyes can't beat what the heart wants to believe.
