"There are no lossless transformations of natural-language text."

Simon Willison highlighted Sophie Alpert's short internal policy on AI-assisted writing, whose load-bearing rule is accountability: "You must stand behind every idea and every sentence in your docs," because you can't excuse a bad passage by blaming the LLM, and doing so wastes readers' time on positions you don't hold (Simon Willison). The underlying claim is the title: every rewrite changes meaning, because the model doesn't hold your mental model of what you meant. Willison calls the accountability requirement crucial and notes the post practices what it preaches by being short. I'd add: this is the correct policy for newsletters, PRs, and design docs alike, and it's an ownership rule, not a tooling rule.
