Meh, saying "five people would have been fired!" is too hyperbolic for my tastes. If you click through to this other HN post (https://news.ycombinator.com/item?id=14671047), you'll notice they don't use proper typographic emdashes (typewriter dashes `--` instead of `—`) and they have a black diamond where their asterism [0] or some other mark would have gone. However, you don't see me commenting there to derail the discussion away from the fascinating topic of these creatures' breathing. In the same way, this is just a minor aspect of the WWDC presentation and isn't such a big deal necessitating people to have been fired for.
