No matter how well I understand something, my ability to relay that information effectively to another individual will always be another matter entirely. It's true that I can't explain something I don't understand, but it doesn't logically follow that I only truly understand something if I can explain it.
It is an entirely different skill to educate someone with your expertise when you don't get their feedback (tv, radio, youtube) or when they don't want to learn (classroom teacher, office politics around bean counters). Those are two kinds of education and they are important skills all on their own but are in no way tied to other kinds of technical expertise.
If we were both working on a project that needed your and my expertise. If I understood that you had different sensibilities about social norms. If I respected those while asking questions about parts of your explanation I didn't understand. Would you be able to explain a detailed topic to me?
Even if the listener knows little to nothing about the subject, being eager to understand and asking questions while respecting my sensibilities, however realistic that expectation may be, makes all the difference for me.
I know of no easy answer but I have met people like this and seen them succeed. I hope you're able to successfuly wrangle this extra complexity that the neurotypical will foist upon you and not even understand that they've done it.
