FWIW, I see talking and listening as a chore, and I don't think many people are good at them. Each is better in different contexts and there is overlap, of course

If you give them something to read and force them to read it, they won’t get half of it because they’re just waiting till the chore is over when they get to the end.

This is not different from talking to someone who is too busy (or just doesn't want) to listen. Writing exists in a form that can always be referenced. There's no risk of playing telephone, no memory required, etc. It'll be waiting for when the person is ready to read it.
