Wonder how that makes the remaining folks feel.
"You're okay because you're not brilliant!"
"Fire that guy. He's clever."
"We're looking to employ second rather than first or third-rate intellects."
Alternatively, build an organisation that brilliant people want to inhabit. Could be useful. Intelligence, that is.
In my view, the difficulty is that the folks making architectural decisions appear not to be so brilliant. The kinds of folks who get to the top by avoiding upsetting the apple-cart. Or who show no sign of intellectual flexibility, like Michael Hayden.
