I think, for folks who grew up in the early 2000’s at least, CLI is the way to go forward. The GUIs at the time were really quite good, it was after the really limited time of the 90’s, but before we started dumbing down GUIs for… I dunno, style I guess.

If you were raised on programs where most of the features were accessible at a button-click, without going through a bunch of hamburgers, modern GUIs won’t feel familiar, CLI will.
