The point is, I'm sure you're not seriously suggesting that every time some new idea comes along, every sysadmin in the world should either be chomping at the bit to spend hours learning about it or be labelled as 'incompetent' and fired.
That's what I was responding to, and it's absurd. Nobody would ever get anything done.
I was attempting to make a rhetorical point, and clearly didn't do very well. I'm not suggesting that wanting to improve one's skills is a bad thing, but characterising anyone who doesn't immediately want to jump onto every new bandwagon as lazy and incompetent is appalling.
