if you say your spouse is a doctor, without knowing they're a pediatrician, something is problematic. you don't have to tell uninterested passersby the exact speciality of this hypothetical spouse, unless they inquire. similarly, you don't have to tell these passersby the language your spouse programs in; but the article is suggesting you ought to know it. (and thus be able to answer if asked.)
