The point is that things that there isn't anything that requires a good engineer that also can be done in a day. Either a job is something that can be done in a trivial amount of time because it's simple, or it's something that's hard enough to take some skill. It's never both. There are no jobs that can be done faster by being a better engineer. Good engineers do better work, not faster work. Often they're actually slower because they consider the edge cases and they don't cut corners.
