The inverse is true: there is a small subset of tasks where a GUI can be so good that nothing rivals it (everything that needs the graphical part and has to have a real time feedback).

For everything else CLIs are more consistent, flexible and extendible.

But why not use both? GUIs are amazing for editing a video, command line is amazing. If you want to convert a thousand videos into different formats based on their meta data the CLI will be the only option that doesn’t makes you sit there for a week.
