In fact, the whole TUI craziness of IT world fashion is getting back to what used to be daily business in the 1980's and early 1990's.
- I like awk grep sed find and many more... and piping things together
- I like the low latency of vim and love walking through code with just a few movers
- I like the ubiquity of using the same tools on any machine, local or remote (including windows now that it has wsl) and bash
All of this even more so than "no mouse setup" or anything, I don't mind using the mouse sometimes.
Simple command line tools become primitives in this language, and they compose together. Learn a few dozen and you have something quite powerful. You can remain in the same mental model to accomplish many tasks. Graphical tools tend to be monoliths that rarely compose, each premised off of a different mental model. This creates friction when moving from one to another.
For better and for worse, the terminal looks pretty much the same now as it did 30 years ago. (There are important improvements in zsh and fish.) Graphical tools tend to evolve quickly. If I don't use a command for 5 years, I can get back up to speed in a few minutes using it's built-in documentation (`--help`). If I don't use a graphical tool for 5 years, I'm pretty close to square one, and need to spend some time with the manual (in a separate application, the browser or PDF reader).
If something is missing from your toolkit, throwing together a proof of concept level CLI is pretty easy. Presumably some people can throw GUIs together very quickly as well. But the CLI is a simpler programming model. (Immediate mode GUIs do narrow this gap, however.)
And now your new CLI can integrate with all your other CLIs out of the box. Eg, a tool that tweaks some values in a JSON file can be used with the `find` command to tweak many JSON files.
(Your mileage may vary. I'm just trying to present a distilled intuition, if I seem to be speaking in absolutes, it's figurative. Whatever workflow works for you is the right one.)
