But how can the sharing economy disrupt the cloud without full-stack agile devops?
It's just a euphemism for 'engineer'.
But you can't be an "engineer" without a Engineering degree from an accredited university, so DevOps.
That's true in some countries, like Canada (where the term "engineer" is trademarked), but it's not true in the U.S. Here, everyone is an engineer.
Unfortunately, the profession is leading the credentialing at this point. I'd expect that to change in the next decade or so, ideally resulting in a useful PE designation (in the US anyway).
