Another way to frame this, which might invalidate/color some of the linked article's points, is to consider "coding literacy" within the context of how the world is moving, and how coding and programming-related concepts are becoming more commonplace and necessary in non-technical careers, and, indeed, in our everyday lives.

In the world these kids will grow up into, having this skillset will be as obvious as having the ability to write one's own documents (as opposed to creating documents via dictation and secretaries/typists), or create one's own presentations. And when being able to program (& I'm using that word loosely; i.e., not everyone is going to be a Haskell dev, but everyone _should_ be able to build "software") is as commonplace and widespread as those previously-technical skills, all kinds of new and amazing use cases will emerge (consider all the things people do with spreadsheets--not everyone is creating financial models...far from it--and the people using spreadsheets to make shopping lists, or organize a Little League roster, or track social media post engagement, are not "Excel Engineers").
