While you are right, I find you a bit rude. If the new generations of developers cannot easily grasp the vocabulary or past concepts of a language, why do you think the new generation is disservicing itself? If the new generation feels disserved by an older language, they will move to, or create, something that better fits their needs. You can't ask everyone to learn the history of everything since the beginning to understand how things were thought initially. Java, the language, is aging. Maybe the author confused terms or didn't used them in the right context, but maybe Java is simply a confusing language that accumulated too many experiments, requires too much expertise or experience to grasp.
