To automate all of services would require rewriting ALOT of software which in turn requires years of industry work.
For example, I give talks at SpringOne, API World at have had Netflix and other state my work fixes alot of their issues. But they would have to rewrite their existing code... and they invested millions into it. Now regardless that the rewrite might only take a month or so, they want to get their investment back FIRST.
So alot of these companies are not going to do that... regardless of the fact that they are LOSING money because they are not automating.
Still, at least they are employing people and that makes me happy.
