I'm not sure what you mean by break, but the comparable time line for Java, and C++ would show far less improvement in terms the addition of programing language

I'm not sure what you mean by break, but the comparable time line for Java, and C++ would show far less improvement in terms the addition of programing languages (as in the academic discipline) features (e.g lambdas, closures). They've done a far better job than most languages of actually advancing the language conceptually, not adding libraries/features.
