We don&#x27;t need to think about AI. I&#x27;d rephrase your question like this:<p><i>What can the author do, sitting at a computer, that later readers can&#x27;t undo?</i><p>When phrased that way the answer is obvious: a lot. Like multiply two large numbers together, or obfuscate a program to make its meaning less clear. Both are in principle possible to undo, but the &quot;load factor&quot; can be arbitrarily large, making the effort for the &#x27;reader&#x27; entirely uneconomic.<p>If even a human can&#x27;t undo some things that the author did, how can we expect the computer to do so?
