I definitely agree with this. Managing complexity is our trade.

Interesting musing on the skills required, why it's actually hard to apply them... clearly it's because you never find a real place to learn them so that ends up being on the job.

Or why I'm actually glad I'm not certified even though I could be. This is a good way to stay balanced about all this. At least I'm trying to do my part trying to help people also on the technical areas which are mostly ignored by the "Scrum Industrial Complex" (as Ron Jeffries puts it). Clearly the scrum organizations are not interested in taking up that mantle so it falls onto us.
