Agreed, but I think that might be our tech bubble. My non-tech family still just types searches in the URL bar of their browser first, and I'm sure others just have google as their browser homepage. I assume that's actually a pretty common use-case for most non-tech users.
However, I specifically use Google (or DDG) when the LLMs are failing me. When I want "research something on my own" because the LLM is giving me garbage, or untrustworthy information. If Google completely replaces their search box my Google usage will go down even further.
I don't plan to use Google's LLM when Cluade is just better. Now that Google's search features are gone (or going away) I no longer have any reason to turn to them at all
