I am writing about learning coding in grades 1-8. 
It is zero sum in that if your curriculum includes coding, unless they extend the school day something else has to go.
No one can seriously say that the clueless email user wouldn't be in that predicament if only he had studied coding in grades 1-8.
Or that those who "intuitively pick up a new software application" owe it all to learning to code in grades 1-8.
If everyone studied coding in grades 1-8 not every one of them would "intuitively pick up a new software application".
