Wouldn't an AI-driven search engine be even better than a language model for that purpose though? It could even snippet highlight the most relevant parts of various web pages to save on the sifting.
Maybe, and arguably, that's what Google has been doing. But one thing I really like about the idea of using a model directly is that there's one interface to learn, whereas with web search, I'm constantly adapting to a grab bag of page types and UX conventions.
