I find people tend to lack nuance in their communication more often - leading to problems and misunderstandings.

If I don't grok an elaborate explanation, I can ask for clarification. If it's explained to me in an overly simplistic or unnuanced way, I'll walk away with a false sense of understanding.

That said, I'm sure we all have very different concentrations of these types of people and problems around us. I've definitely met some engineers who seem to actively try to make their language incomprehensible

I'm going to assume it's very difficult to assume what a user actually knows from the very small signal that comes in a prompt.

effective communication is knowing who the audience is. Everyone naturally knows their audience to some extent, except for the "neuro-atypicals".

It is unsurprising that a LLM fails, without coaching, to effectively communicate.
