I think a lot of cutting-edge work is also done at the edge of understanding, and that's fine. It can be hard enough to explain groundbreaking work to experts with deep context; it's reasonable to me that it takes more time and work to find the explanations that make sense to the average person.

I do agree that researchers should be able to give decent "here's what I do" explanations to the general public. But that's very different than a member of the general public understanding the context well enough that they can judge the value of the work to the field.
