Google search has seamless integration with maps, with commercial directories, with translation, with their browser, with youtube, etc.
Even though there's more than a few queries they leave something to desire, the breadth of queries they can answer is very difficult to approach.
But for me, if I want to look up local restaurants, I go straight to Maps/Yelp/FourSquare(RIP). If I want to look up releases of a band, I go straight to musicbrainz. Info about Metal Band, straight to the Encyclopeadia Metallum. History/Facts, straight to Wikipedia. Recipes, straight to yummly. And so on. I rarely start my search with a general search engine.
And now with GPT, I doubt I even perform a single search on a general search engine (google, bind, DDG) even once a day.
Back before I found Kagi I used to use it everytime Google failed me.
So, yes, given he is the only one I know who manages this it isn't trivial.
But it clearly isn't impossible or that expensive either to run an index of the most useful and interesting parts of internet.
