It's also interesting that the more you become an "expert" in a specific area, the easier it is to recognize that everyone else seems to (at best) simplify and dumb-down that topic. When I listen to a podcast with smart people (who are experts in their own field), they seem to get trivial things wrong with my field. I'm sure that I do the same anytime I try to communicate about their field. I hope that now that I recognize that others have difficulty with the basics (or nuance) in my areas of expertise, it moderates my confidence talking with others and limits any "why didn't they ..." moments I might otherwise have.
