For me personally, it's about putting the right amount of emphasis on your tools. Using your mouse shouldn't be outright verboten, but I do see your point about having a properly set-up editor. I could probably be 30-50% more efficient with just the right vim config. For reference, here's mine:

$ ls -l .vimrc ls: .vimrc: No such file or directory

However, as a counter example, instead I've spent time on learning how to use Ansible which lets me automate parts of my job in a way that just wasn't feasible 15 years ago. To me that provides a much larger benefit (easily 10X, maybe even 100X).

I guess my point is that I don't want to spend too much time on the plumbing part of technology and leave figuring that out to someone else - much in the same way we're using libraries nowadays instead of re-implementing hash tables ourselves in every new project.
