"I'm not going to claim that there are no legitimate reasons to hire people who are narrow experts in Blub (and only Blub), but I'm having a hard time thinking of any."
Blub is a very useful tool but has a bunch of quite esoteric gotcha's that an expert will be able to avoid due to long experience.
Expert has used almost all of the Blub framework over the years, including the more popular third-party addons and already knows what's best and fastest in a variety of situations without having to think about it much.
"A truly good programmer will pick up your language/framework in days, and be at full productivity in months, even from scratch. It's hard to do better than that."
Yeah, but then HR won't be able to tick off the 'Blub expert' box and, well, nobody would ever get hired! Or something...
