Earlier quoted context omitted.
I feel like at a certain point of efficiency there are diminishing returns. A good analogy is typing speed. You don't need to have 200 wpm to be productive. Everybody adapts to how efficient they need to be at what they do. Vim is not a requirement for being productive. If it was, it would be the most popular editor. I also don't think the person you are replying to is saying that it isn't important to "master" your…
You don't need to hit 200 wpm but I haven't seen too many programmers who hunt-and-pecks at the keyboard and can't touch type. Even on a Qwerty keyboard you should be able to get high double digits, if not hit/exceed 100 wpm. The two sites I like for practice are: https://monkeytype.com/ https://play.typeracer.com/
And when I write I just need to see the keyboard with the corner of my eye and my fingers just find the right keys as I'm pecking, purely through muscle memory that I've gained with zero effort just by years of experience.
