if we are going to complain about AI content then i suggest we also include some evidence to make the argument at least somewhat insightful. i'll start: pangram gives this a 100% score (without the sources section), on account of the em-dashes. remove those and the score drops to 49%. include the sources and the score drops to 36%.
(edit, i misread the score: after removal of the em-dashes the result is 48% generated and 49% assisted, add the sources, then it is 33% generated, 36% assisted, and 30% human. i didn't check the original text including the sources. i ran out of free credits.)
