I think he misunderstands the command line. If you have tasks you need to do a lot, such as compilation, committing a change, and so on, it's easier to use a GUI or key shortcut. There is no "badge" in typing "git commit" or "make" as you know them by heart soon enough. But for specific manipulation of the version control system, or specific queries, a command line is much more expressive. For a lot of functionality there isn't even a (good) GUI because the use case doesn't come up enough for someone to build it, or you're doing something no one has thought of before. Sometimes you need to take the path less traveled :-)
