Many portions of Magnifica Humanitas appear to be AI-written
lesswrong.com- I took the French version of Magnifica Humanitas, chapter 1 paragraphs 21-24, which is supposed to be AI written at 63% and Pangram says it's 100% written by humans.
- Conversely I took the entire post by Daniel Filan and PanGram says it's 55% written by AI!
