LLMs are doing things like summarizing videos and then using the summaries to answer queries that before would have been a search result with monetization.
Google's executives are unconcerned about the declinibg incentives to create YouTube videos having been sold on the lie that the future of the internet lies in Ai generated content. In other words robots will make the internet.
Robots which hallucinate constantly.
Even fun videos get search traffic from random queries. A video about robots fighting each other will get traffic from people interested in "robots fighting", "robots wars", "robowars", "armored core", "Gundam series"
When there are ai summaries for informational or navigational queries there will be fewer clicks because Google will pirate listicle sources of "best robots fighting each other articles". This means they are stealing from older lists and newer videos will not get mentioned in the ai summary.
This is because ai technology can't judge the quality of a video.
