Would be lovely, but many issues. 1. If LLMs can't reliably produce factual information today, how can they check if any statement is factual? 2. What about writing that is not recounting facts? e.g. fiction or marketing? 3. who decides what is factual? Does the system give a pass to statements like "full self-driving" or "AGI" or anything accompanied by "the likes of which have never been seen before"?
