Imagine if we invent a reliable way to encode any encrypted payload inside a regular Kind 1 post. You can make an AI account that is just posting silly stories. Each story is its own encoding scheme (like base64) for the encrypted information underneath. The encoding algorithm just so happens to output fully correct, and even enjoyable, sentences out of it. Most people will read them without realizing they are actually encrypted information being transferred in plain sight. If they include a significant amount of error correction, humans can transmit machine knowledge by just telling stories to one another. And we love to tell stories. 

We already do this in pictures, with today's LLMs we can start doing it with text.
