Anyway, I think the issue of "not enough programers" is different to "not enough people can code." To keep beating the old writing analogy. One is "not enough scribes" and the other is "not enough literacy." At some point in history professional writing and literacy stopped being substitutes for one another.
Normal literate people didn't compete with novelists. Or looking at it another way, printing presses and literate public completely removed the need for scribes and (I think not coincidentally) we got lot more writers shortly after: novelists, pamphleteers and scholars.
So nurses who can code will not replace the programmers who wrote healthcare.gov but they might do different useful things.
