Maybe the sort of "Redhat certified" sysadmin you get these days can't even shell-script and they think this is some radical innovation.

No, sorry. I'm not going to let you get away with that.
Have you ever actually looked at or done any Redhat (sic.) certification? I have. If you compare it to any other certification at all, you will find the exams much much tougher. I passed all of them first time, most (RHCE) or the majority (above RHCE) definitely do not.
I think dragging in Red Hat certification really weakens your argument. What does being Red Hat certified have to do with knowing how to shell script? Nothing at all. If you want someone who can shell script, _ask_them_if_they_can_shell_script_.
It's a simple question, but don't drag down people who've got certifications, particularly this certification, to make your point.
If you're working on a team that is responsible for both then devops isn't a useful concept - you're probably doing it already. Many people are not so lucky.
When you have a big complex environment with thousands of servers all running the same code, it makes sense to start treating the hardware itself like software components. All modifications to hardware can be committed to a central SVN repository and pushed out with post-commit scripts. As long as you can script all types of OS patches, firmware updates, etc, using some type of language and an automation tool like Puppet or Cfengine, this can be done.
For a large company like Google or any cloud provider I'm sure it makes sense to start treating your server infrastructure like software components and have the same type of change control, QA, and deployment methodologies wrapped around it.
Hell, I don't even have commit access to the corporate SVN repository, so why would you expect me to be a cowboy and fix bugs on production systems?
I'm happy to help automate deployments, etc, but you stay away from my Perl scripts and I'll stay away from your code, thank you very much.
