I think that this isn't always the case. Some peoples' brains (such as mine, I believe) are more wired to be symbolic. I suspect that, for these people, using a textual-command-oriented CLI interface is going to be noticeably easier/more intuitive than those whose brains are wired to be more visual/kinesthetic/whatever else there might be.

The modern GUI interface doesn't seem to share many characteristics with non-computer parts of the real world.
