It's possible to run Ubuntu 20.04 or 22.04 completely from the GUI, assuming of course that your applications are GUI (browser, mail, office apps, etc.) and that the GUI-based system config and update apps do what you need (likely true for most users).
As a system admin, I've lived in the command line (terminal) by choice for many decades on every system I work on (Linux, Windows, MacOS) but that's not required for normal user operation.
Yep, most of the most popular are simple full GUI for the average user. And as you know, GUI Linux apps are universal. They work on all Linux old or new. :)
Yeah, exactly. I use Windows and I’m in a command window all the time, so that’s not a barrier.
