The issue is that employers are horribly inconsistent. They demand specialism in hiring, but refuse to respect specialties once they've pulled people in. Thus, you end up having to interview like a real computer scientist, only to find that most of the work is mind-numbing for a serious programmer, but that there's no one around at-level for it because "we only hire A players".
DevOps didn't do this. The problem is the industry, not one concept.
