Comparing your first sentence and that of the author, you're missing what I see as the key word: "skill". I use command line everyday. Probably most developers do as well. But I definitely don't have "skill" in it. I think the point is that most developers can get by with nothing more than the basics (whatever "basics" are in the context of their work). The command line isn't archaic, but command line as a fluency might be.
