To be honest, the command line is an important tool, that when you are able to use correctly, will give you a better understanding of a lot of the inner workings of a machine.
The commandine might be intimidating at first, but I personally think not as big of a hurdle to think about replacing it with anything.
Most people that I know that at first were afraid of the command line but tried to get into it, now don’t want to go back. Working with the cli is so efficient that it’s hard to go back to GUI’s.
Edit: don’t get me wrong. I do love a good gui! And I am all for creating usefully GUI’s, also for tech jobs. But I don’t see a point in replacing the job you do in the cli with a GUI.
