It's funny cause the more advanced/skilled you get in general computing, the less GUI you use. You can usually spot someone who is a yee-old master when you look at his desktop and it's running without any graphical desktop environment, straight CLI only. GUI is to humans what WINE is to Linux trying to run Windows software, it's an interpretation layer that helps us understand in our primitive ape like senses. Computers languages are more efficient than human languages/forms of communication with all their nuances. Everything that has moves away from the keyboard, e.g. touch screens, big shiny icon tile UI's, etc is a lot slower and less efficient.
I would argue that this sentiment is only true in very niche cases. The most common thing you'll likely do on a PC is launch a program, and double clicking on a shortcut is a lot easier and faster than typing "cd C:\Program Files (x86)\Steam\Steamapps\Common\Skyrim" followed by "run tesv.exe"
The reason you see power users with terminals and command prompts open is because they're trying to do something advanced that the GUI doesn't have support for (like reinstalling Edge with Powershell because it committed seppuku) or are creating a batch file that does several different tasks automatically. However, GUIs are generally designed (or should be) so that the most common ways a user interacts with the device are made easier AND faster.
There are no problems, only solutions I have yet to enunciate.
But what about those of us who can type without looking on QWERTY?
I figured that for the most part, if you're on this site you should be able to type without looking at the keyboard. Maybe I'm wrong? I'm no a CLI geek by any stretch but if you graduated high school after Windows 98 was released, you probably know how to type.
