Right, all good (human) communication boils down to both the author and the reader having a theory-of-mind for one-another. The writer must anticipate what a reader will be thinking, and a reader must imagine [0] what the writer wanted to convey.

That's part of what makes the modern epidemic of LLM slop so frustrating: The correctly-formed words make us waste effort trying to reconstruct a mind that was never really there. Like some animals encountering an extremely realistic plastic fake that we cannot eat/mate-with.
