I find that CS introduces very few layers of abstraction in the true sense of the word "abstraction." Even its classes are just syntactic sugar for existing semantics. My (mild) knock against it is that it doesn't introduce any new abstractions. No special sauce for continuations or promises, for example. But that is obviously a two-edged sword, it eschews new semantics by design.
