Simon Willison's central point exposes a fundamental, often overlooked, consequence of delegating editorial tasks to AI. While the industry focuses on AI's ability to generate or refine text, the potential for semantic drift—where the core idea is subtly altered or diluted—remains a critical, unquantified risk. This isn't just about grammatical errors; it's about the erosion of nuance and personal voice, which are essential for credible communication.
In our view, this suggests that the most valuable AI writing tools may not be those that rewrite best, but those that most clearly surface and justify their changes for human oversight, treating the author as the final, responsible editor rather than a passive recipient.
