We love our editors because of compound interest. I think that's really the takeaway here. Spending time in your environment allows you to accumulate skills that let you solve pretty much any text based problem you can think of. Whether that's using emacs with elisp or vim with shell scripts and Unix tools isn't important. It's having that playground of an environment to solve arbitrary problems.
