by far this is the least math-dense and most intuitive explanation of these ideas that I have seen committed to print anywhere. consider that you might need to do the work of developing improved personal understanding, rather than complaining the expositor hasn't done the work of getting to the conceptual essence. sometimes the conceptual essence is mathematical, cannot be further compressed, and that's okay. I struggle to see how this blog post could possibly be "simplified" beyond defining a few terms more explicitly.
