It's definitely the beginning of the end of Google Search IMO. Extremely small sample size, but me and many people I know have started running the majority of searches that end in a question mark (actual questions) in an LLM, and not Google's LLM. Google is only used as a sort of phone book - when I need to look up the URL of a site by inputting the name, or when I want to find a particular article I previously read. I would say my usage of Google has reduced by about 75% (seat-of-the-pants estimate). It's just better to do it this way, and I have to imagine that this sentiment will spread.

Google will have to survive on other products, like YouTube. I see a massive contraction of their employee base in the not-so-distant future. Low-return products that are subsidized by the massive revenue of search will likely be cut as well if they can't be monetized more effectively (which will ruin them).
