Part of the problem, and what ultimately drove me out of coding altogether, is that Ops is a specialized skillset completely orthoganal to the business of building applications. And, I was really bad at it due to a complete lack of interest. As cloud environments get more and more complicated one ends up spending more and more time dealing with that at the expense of building things.

Conversely, there are lots of folks who love ops type problems and are not well suited to building apps. So, it makes sense to put them on separate teams where they can each do the thing that they're best at, rather than fumble through the parts of the jobs they hate. But yes, at this point it's not really DevOps anymore, it's just ops.
