Hard disagree. The fact that they have customized their system to such a degree shows they do know how to use computers. I think you're trying to conflate that with other things like programming ability, which are orthogonal.
Wrong. Knowing to customize a theme != knowing to use a computer != knowing how computers work.
I can say I know computers and how they work pretty well, but these days I have much better things to do to learn the best way to themes my shell so that it matches my waybar, and that both switch colourscheme when dark mode activates. I could learn if I wanted, but I’m not a teenager anymore; I don’t care. Incidentally, when I had the time concern myself with GTK themes and wallpapers and Compiz, my knowledge in computers was a tenth of what it is now.
It would be like saying a car decorator is the most expert of mechanics.
This. Nowadays I just use Zukitre for GTK/Qt and the Tango icon theme, it suits
TWM/CWM and any other minimal WM without tons of effort. A dull gray theme combines with everything, even with my Cyan titlebars for TWM (they make a great contrast with red borders and wheat yellow icons/menus). You know, I want to use my computers and the titlebars stand out like crazy. And, actually, I've just borrowed an old color config used from a university.
The background?
xsetroot -solid gray20
I never understood the trend on dark/bright modes; the gray themes from my childhood/early teens with W98SE (and used by Mac OS 7/8 too) are just neutral and barely 'sit there'.
