I think the scale of applying AI to generate contents will cripple search engine even before your scenarios become true.

I have a hobby with natural photos, and in the last 2 years, I have stopped spending time browsing pages as most of them are garbages generated by AI.

One thing many people hype about generative AI as they believe human also make mistake the same way as AI do, so at worst you have something similar to human mistake. Yes, but the volumes generated by AI are at magnitude bigger, and only a limited amount of human can validate and filter it out. If there is nothing change, this volumes of garbages will surely overflow and there is no way we can differentiate bad and good, fake and authentic contents.
