and at the risk of tooting my own horn a little... I do kinda think I'm pretty good at adapting the level of detail to an audience, and teaching people

As someone once said: if you can't explain something to a six year old, you don't understand it yourself.

If you can adapt your explanations to your audience then you're obviously understanding it properly yourself.

Aero is simple, but simple does not mean easy. A knife is simple, using it, ain't.

A bit like the response to the admonition "get on with it, it isn't rocket science!": rocket science is easy, rocket engineering isn't.

Or you just can't speak to 6 year olds.
