> who's using search engines these days

If nothing else, how do you think various LLMs using tools are doing their web searching?

Besides, plenty of people resort to traditional searches for various reasons, often because LLMs aren't happy to talk about any topic, while search engines usually lets you search for pretty much whatever you want.

People who do not want to read and trust the slop that whatever LLM du jour is regurgitating after calling out to said search engines.

Humans are already unfortunately prone to bullshitting and bloviating, but they are also used to dealing with other humans: there's no need to add an additional layer of both from a black box which does not behave like one.
