Yeah, I'm referring to the anecdote about hiring the new developer and expecting them to immediately contribute to bug fixing a mature project. Forget about any disruptive personality flaws the programer might have (which I agree is probably another factor to consider), I read this anecdote as an avoidable worst case management failure scenario and a potential straw man for his argument. So, maybe a little to negatively ideal to serve as a point of reference for his argument.
