The paper linked to in the Criticism section of the article [1] is well with reading, IMO.
It points out that AOP only works when there is "obliviousness of application", i.e the code to which the aspect is applied doesn't need to know about the aspect, and argues that this kind of obliviousness is pretty rare.
