Google Search has long since diminished from it's peak. 15 years ago we used to play a "game" by describing something as vaguely or strangely as possible and would be entertained to find it still on the first page of search results.
SEO and paid ranking caused a steady decline in Google search performance, and LLMs are the kill shot.
Indexing and ranking were already a solved problem, and conventional algorithms accomplished it much better than LLMs do. Unfortunately, LLMs need to find uses to justify investment, so now they must be used for any task that they can be used for, even if its worse than the solutions that we already had.
