Web search and a chatbot AI are two vastly different interfaces with different aims.
At this point, with a mature Web and a mature toolbox, I know a lot of research tools and resources that I can tap before I get out the sledgehammer of Search or LLM. So, if I know a priori that it won't work to plug a term into Wikipedia, or Wiktionary, or YouTube or something, then I can choose Gemini or Google Search.
If I go to Search, then my query means "I want to find external links and find a resource to research this term". If I go to Gemini, that means that the term is probably out of my wheelhouse, and/or I really want to delve in for some insight about this term, and I probably do not want to poke 3rd-party sites about it.
The trouble is that Google sort of melds them into the same-same, either way I choose. It wastes resources and browser-page-real-estate on that AI summary that I've got to skip and sift through the Search misses. The LLM still insists on a RAG web search and refer me to some dumb links that I didn't want.
Google was famed for its fast searches and rapid results. They used to be good results. But today it's obvious why everyone let Search products decay into garbage: because LLMs were coming, and LLMs are going to supplant your standard searches anyway.
