Not to mention the fact that the remaining sites that can still hold on, but would just have to cut costs, will just start using language models like Google's to generate content on their website, which will only worsen the quality of Google's own answers over time, which will then generate even worse articles, etc etc.

It doesn't just create a monetization death spiral, it also makes it harder and harder for answers to be sourced reliably, making Google's own service worse while all the sites hanging on rely on their worse service to exist.
