If you figure out how to do something in the terminal, you've got an 80% chance of that technique still working in a decade. If you learn how to do it in the GUI, your chances in a decade are more like 10%.
System management utilities should have a GUI, or at least a web UI. I have a really hard time remembering the specific commands to look at my docker instance and overall system health... There's absolutely no reason to not have that all in one dashboard.
Agreed. I tried to avoid using virt-manager for my vm’s.. I get that it is more powerful from terminal, but man is it a lot of information to learn how to communicate.
