Well, I'm in the gaming industry right now, so at the very least learning how to code could just fill out my skill set. I think there is a difference between pushing something like coding vs teaching or nursing. Yes, in many cases pushing people to enter those fields where there was a deficit at the time will flood them with applicants later on. However, we aren't really building many more schools or hospitals. But more and more companies need people who can code. And more and professions rely on, or at least benefit from knowing how to code. Years ago animation had nothing to do with coding, but now knowing python or action script is almost required.
