I don't understand the relevance of your point about CS curricula. My comparison was with respect to my ability to read research papers written by professors, not to do classwork at my current level. I'm observing that math papers are much more difficult to understand and inferring that the state of the art in math is more complex than the state of the art in computer science.
It was partially a tangent prompted by your comment. I meant "the stuff CS people do and think about" not just homework or research. Through whatever accidents of history, practical concerns, or being a young field, the stuff CS people do tends to be easier than the stuff math people do, but that doesn't necessarily need to be the case.
