I think so, too. This doesn't mean the CLI is less discoverable (assuming good design), just that active knowledge is harder to aquire than passive knowledge. Passive knowledge is enough to use a GUI, because you can just see where you need to click. There's a lot of "information in the world".

I find that CLIs are usually a little bit harder to learn, but often so much faster if you've learned them, that all professional developer tools should at least have CLI as a possibility.
