For an idea of how far the average US physics education has been dumbed-down in the past three decades, I doubt a 3rd year US-educated physics graduate student could pass a test on any of the chapters.
As for the uncovered subjects, it turns out quantum mechanics occupies a large space of the "new physics" that graduate students are trained to do.
There are definitely an incredible amount of utility and knowledge to be gained from the classical field theories, and obviously many outstanding and new problems that I think need more attention as well. At the same time let's not understate the utility of quantum mechanics that most grad students are specializing in.
You are speaking out of turn.
