Dead internet theory

Earlier this week, it was discovered that the Chicago Sun-Times and the Philadelphia Inquirer had both published an externally-produced "special supplement" that contained facts, experts, and book titles entirely made up by an AI chatbot. There's been a lot written about this (former Chicago Reader editor Martha Bayne's is the best), and I don't need to rehash it all. But the thing that is most disheartening to me is how at every step along the way, nobody cared.
