That's true, but most people underestimate how opaque their writing can be even to other experts. It doesn't mean you have to explain every piece of jargon, but you can often greatly improve the clarity of your writing, including for expert readers, by targeting at least a few levels of expertise below where you think your audience is. We all have gaps in our knowledge that will seem basic or obvious to others, no matter how expert we are in a topic.
