I think the focus on speed is counterproductive. Increased productivity isn't the only — or even the most important — measure of value.
I enjoy using Vim (Emacs Evil mode these days) because I can edit more fluidly without having to shift focus and context switch. My hands stay on the keyboard, my eyes stay on the screen, and I don't have to think about "how" to achieve my goals — I just think about what I want to achieve and muscle memory takes care of the rest.
I might edit more quickly, but that's a side effect of using a tool that allows me to focus deeply and maintain that focus for longer: both of which are vital to flow and satisfaction with my work.
