It's a bit elitist[1]. They're saying we should expect 3x better performance from engineers. We should also expect them to write good code at this pace. The only reason we don't have these things is that most engineers are simply bad engineers. Only people the author perceives as good enough should ever be used as a metric of normal productivity. Presumably the author puts themselves in this group of good engineers. 1. https://en.wikipedia.org/wiki/Elitism
