He mentions the point when the abstractions in the language are no longer sufficient. It seemed to me that this was more an argument in favor of using languages that are easily extended rather than languages full of abstraction with few options for extension. If you use a language like the latter, you'll still eventually reach a point where the abstractions aren't sufficient, but if you use a language like the former, though you'll reach that point sooner, you'll be better equipped to handle it. edit: word use
