Linux

There is a bit of bias in your assumptions as illustrated by the “use the man page” step.

It is not always true that GUI means easier or more intuitive. It almost never means faster which is why terminal people like the CLI so much.

One of the major benefits of the command line is that it is almost universal between distros. Package management is one of the few things that differs between distros so let’s use that as an example as even in this case there are only a handful of package systems across dozens of distros.

I know that apt install and apt search work across the entire Debian family including Debian, Ubuntu, Mint, and Pop ( all different GUIs ). If I was at a random Linux command line in any distro, it would take me moments to try apt, dnf, pacman, and zypper. Without even knowing what distro I was looking at, I could be managing packages in 10 seconds. I bet one of these would work on your machine. The commands that did not work would be harmless. In contrast, it would take me at least that long to find the “store” in a menu ( if I even knew how to bring up the menu ). There are almost as many software stores as distros. Some distros have more than one. Once in the store, I would have to discover how to do what I want. I have never used most of them. In half of them, finding out how to do a full upgrade may take a while and I am not sure how confident I would be that it was going to do what I wanted. I may really be lost if I got any errors.

I use an old MacBook every day and booting into Xfce I can type “yay -Syu” before the wallpaper even comes up and certainly before a store would launch. I can also ssh into a number of other machines and update their packages remotely with the same command. Getting a Remote Desktop would be far harder and what methods are available to do that vary from machine to machine. It would be far harder.

Anyway, this comment is way too long. My point is that, for many people, the command line is faster, easier, perhaps more intuitive, more consistent, and often requires less to remember than the GUI. Windows just added a “sudo” command. Why would they need to do that if they are the poster child “everything in the GUI” OS?

It is great to have GUI options and clearly some people will did that less intimidating. That said, once you start using the CLI, it is painful to go back.
