I showed some old Olga Tokarczuk essays to my friends to pick what was ai slop and what was not as experiment, pre- 2020 ones from Czuły Narrator to be exact. Guess what, they picked the ai one as human and her as most ai. Maybe because she uses a lot of big words and em dashes.
We are at the point, when there is too much cognitive energy needed to discern writing from human, human ai assisted and all ai. Should we know make mistakes on purpose to avoid being labelled as ai slop? :)
