I don't know if it's satire, but I can't take this article seriously. The command line, for me, isn't about doing things the hard way. Nor is is necessarily the easy way either. It's an alternate interface which has some strengths.

What is compelling about the command line is how it can be it's own ecosystem and it's possible to use most of the features of a computer within this constrained environment.

It is not really quicker on the GUI

Regular users rarely type in commands. Either reverse search or zsh/fish/bash auto completion makes it much easier to run something in one two key strokes compared to few clicks in a GUI. Also switching to mouse from keyboard constantly slowes you down.

The inefficiency of mouse as interface is best illustrated in Excel which has power user shortcuts for every menu item. Expert users will never use the mouse if they can avoid it for the same reason. IDEs and many other apps work the same way.

Finally for developers who hav to work with servers, You don't have the luxury of working with GUI, you will have to learn these kind of commands anyway, using these locally on your desktop is more convenient.

I literally do all of these on the command line except for using a calendar. Using a GUI is fiddly and terrible.

Which isn't to say everyone needs to feel like I do. But some people at least will strongly disagree that the GUI is easier.
