There are no lossless transformations of natural-language text

There are no lossless transformations of natural-language text Sophie Alpert shares her "internal policy on acceptable use of AI writing by engineers". It's a short read (supporting its own recommendations) and really good. If you chose to have LLMs help massage your writing the following rule seems crucial to me: You must stand behind every idea and every sentence in your docs. It is your responsibility to make sure that the entire document is representative of your own thoughts before you s ✦ AI generated

01
Claim

Document authors must stand behind every idea and sentence in their documents and ensure that the entire document represents their own thoughts before sharing it.

Before sharing AI-assisted writing, an engineer remains responsible for verifying that every part of the document reflects their own thinking. They cannot dismiss unclear or inaccurate text by blaming the AI, because doing so confuses readers and wastes their time.

transcript

Sophie Alpert: You must stand behind every idea and every sentence in your docs. It is your responsibility to make sure that the entire document is representative of your own thoughts before you share it. If a reviewer asks, “What did you mean by this line?”, it’s not acceptable to reply with “Oh sorry, AI wrote that, just ignore it.” You will confuse your readers (and waste their time) if you present them things that are not genuinely representative of your thoughts.

02
Mechanism

Natural-language text cannot be transformed without changing its meaning, and information is lost when the transformer lacks a detailed understanding of the author's intended message.

Every rewrite or rephrase alters the meaning of natural-language writing. When an AI or other entity performs the transformation without fully understanding the author's intended meaning, some information will inevitably be lost.

transcript

Sophie Alpert: There are no lossless transformations of natural-language text — every rewrite and rephrase changes the meaning of your writing, and if this is done by an entity that doesn’t have the most detailed mental representation of what you personally were trying to communicate, information will be lost.
