Just like there's no difference between saying, "Could you pass the butter, please?" and pointing at it and grunting. :-) Using a command line encourages a person to explore what they can tell the computer to do, rather than accept what a GUI allows them to do. It encourages learning that you can put a list of regularly used commands in a "script" and then re-run them. And then exploring what else can be done with a script.
