“I think for junior and mid level ICs, and leadership/management focused people (maybe even senior ICs), speed is paramount.”

Why? I would argue they need to move slower and methodically so they understand what they are doing instead of thrashing a bunch of crappy code that has to be fixed by others.

More experienced people can move faster because they are doing tasks that have parallels to prior tasks. For example, Keanu Reaves was able to singularly focus on “gun fu” as he is an experienced actor for whom remembering lines and handling himself on set is second nature, requiring less effort than from a rookie actor.
