No doubt, if you're working in AutoCAD, there's no command line that you need to understand first.

But then again, if you're working in AutoCAD, you'd never say "I used to work in CLI only, now I use GUIs more and more".

Clearly they meant GUIs that have CLIs behind, or at least CLI alternatives.

AutoCAD is an unlucky choice of example here, because it's one of the few GUI drawing tools that actually does have a command line behind it that you have to understand sometimes! Look up a screenshot of AutoCAD and you can see the command prompt at the bottom of the window.

And if you were using AutoCAD in the 80's you can say exactly that you used to use the CLI only!

CorelDraw? Word? Audacity?

Or maybe it will turn out that all GUI software has command line somewhere inside. I think my original point stands even better in that case.

Yay for hair-splitting, I guess.

"Or maybe it will turn out that all GUI software has command line somewhere inside"

Not at all. Most maybe, but since I wrote GUIs without a CLI I can say for sure that not all have them.

I mean, every web GUI, which are now probably the majority of GUIs do not have a CLI anymore..
