It is not fashionable nowadays to speak of the merits of the command line, in an age where things like streaming video and Aqua are an integral part of our daily life. However, I do not think that typed-in commands must necessarily be consigned to the dustbin of computer history. Of course, I am not suggesting that we all drop X and Windows and pretend like we are living in the early eighties. The command line interface still has much to offer us, and many of its benefits simply cannot physically be emulated or even replaced by graphical ones.
Too much sys admin is cli-bound?? I hope you are kidding. You can see them copying more and more of Unix Cli in their windows servers.
Now that you mention it, I heard that Microsoft is developing a GUI-less version of Windows Server. I don't know if that rumor is true, and I sadly don't have any source to back my claim, but I guess that a GUI-less version would be better and more efficient than a CLI-less one.
