I refuse to be old man who yells at clouds, but I think just like the new gen can't help what comes, neither can I. I just feel so old sometimes because most of the "new ideas" aren't really at all; they just have a different language to describe the same thing.
There's a good ratio between the time it takes to implement a TUI and its usefulness.
Writing a GUI with equivalent functionality would typically be a lot more work, with no gains at all. Er, except maybe touchscreen and touch-gesture support, none of which would add any value for this kind of tool.
I disagree. Have you used something like tkinter? It's ridiculously easy to build GUIs. The trouble is if you build a GUI that way it will look kinda beige/crap whereas a TUI looks retro (but looks even worse to non-nerds).
So there’s another issues with GUIs, they might be fine on Xorg and have issues on Wayland (or viceversa). TUIs all work as long as your terminal emulator works.
I want a GUI when I don't have a keyboard, typically on my mobile phone.
