In the past, I've been interested in things like the Dvorak keyboard layout and old text editors—namely vim and emacs. Why is this? In specific domains, these tools confer some neat advantages. To summarize, the Dvorak keyboard layout gives a more comfortable typing experience as the letters are arranged in such a way that you can type the most common letters without moving your hands from the "home row". Key presses are more balanced between your right and left hands. Vim and emacs are both text editors—programs used to type stuff. For programmers, system administrators, and other "power users" being able to quickly create and edit files is a valuable skill.

Practically, however, the world has moved beyond many of the applications for these tools. If you were tasked with choosing how to do information technology in a small community from scratch, you very well might teach these tools and keep things simple. People would be able to work very efficiently and wouldn't need to learn much more computing beyond some basic UNIX stuff.

However, in our modern world, this is not the case. It would be a real pain to try to retrofit emacs or vim or some other old editor to try to program in the "new style" of web frameworks like Angular or React (yeah yeah... I know it is a "front end library"!). Simply put, "modern" software development is designed for "modern" tooling.

To work on mastering cool old tools can be educational—you are studying case studies of things that worked well with certain limitations. LARPing as a 90s programmer and using vim to do everything may be a fun way to practice solving some well-defined problems by writing simple command line programs. ¹ However, for "real world" applications (that is, what bosses might demand) you are probably better off just using whatever the current "industry standard" is...

This is my basic conclusion from enjoying using lots of "retro" or specialized stuff/techniques—it isn't worth it to try to do things in a different way if it isn't paying. Take the lessons from it (e.g. keyboard commands are useful) and then move on; it is not worth the overhead to try to customize the world to your idiosyncracies. Just be normal!
