1) identify something as AI-produced
2) attack and ostracize anyone who might be involved in that production
And as with all moral panics, whether (1) is factual is totally beside the point. The point is the almost sexual release you get from (2).
I know in this case there is AI-produced code in rsync (as there is with most useful software by now), but you see the witch-hunts every day online and as with all witch-hunts it really doesn’t matter whether the accusation is true. The hysteria is the point.
