There are no lossless transformations of natural-language text
Every AI rewrite of human text loses meaning the original author intended
“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.”
Sophie Alpert articulates a policy for AI-assisted writing that centers author accountability: engineers must own every sentence AI helps produce, or risk confusing readers with ideas they don't actually hold. The core insight — that no AI rewrite is lossless because the model lacks the author's full intent — offers a principled framework for where AI writing assistance breaks down. Relevant for teams setting internal AI usage policies, though more of a best-practice piece than a major industry event.
