You do need rapid feedback to know if you've made a mistake typing at 110wpm. Latency also makes a terminal feel like molasses; just sticky and unresponsive.

  I agree with both you and the parent comment :) Yes, I don't even always need to look at the screen when I am typing fast. However, when I do, molasses UIs make me sad. As an interesting aside, I notice that my brain tends to make interesting typos when I am typing without looking at the words that I type and get into a flow state when I am not thinking about the spelling of words, especially at high WPM. By "interesting" I mean "I would have never consciously chose to spell that word like that" interesting. It shows that typing is happening on a different level than spelling; it's a more direct pipeline than writing with a pen where one has to think about shapes of letters. It sort of happens as an independent process, where <send a word to keyboard> happens without active thinking, and can have interesting "optimizations" along the way. I am looking at the monitor to make sure that these "optimizations" do not, in fact, occur. To give an example of this, here's a snippet of what I type with my eyes closed: "I'm a rocket ship on my way to mars, on a collision course. I'm a sattelite, I'm out of contrrol. " So, I need to occasionally look at the screen to catch "contrrol" errors. And it's annoying to do so when the letters lag behind key presses :)
