At the risk of not only stating the obvious, but also sounding like a prognosticating blowhard… I’d say that developers with a skill-set that only involves programming to a spec should worry about being automated out of their jobs.  This has happened countless times through our history of near-continuous economic revolution and there’s no reason to believe that it can’t happen with software.  (that was the blowhard part) The frameworks we code against have increased in sophistication and utility a tremendous amount over the last decade, and the previous decade for that matter, though it seems to be accelerating.  What was once many lines of code is now few and I expect this trend will continue.  Add to that the coming (this is the prognosticating bit) rise of domain specific languages and you can see that the design and the code will be converging and folks who make their living off the current delta are going to feel the squeeze.
