Can you give examples of the average pre-ChatGPT Google queries you were doing, that ChatGPT can fully handle?
Personally — and having not tried ChatGPT for this — I don't think ChatGPT would do well with resolving the kinds of queries I consider Google "good at."
To me, the place where Google wins over Bing, DDG, etc. is when I know there must exist some page that uniquely talks about some extremely niche overlap of concepts; but I don't know any specific "natural key" keywords to refer to the that overlapped-set-of-concepts, and instead only have a "cloud of highly-correlated keywords for the individual concepts involved" to throw into the search box.
For example, if I'm trying to conjure from the aether a discussion people are having about an issue I'm facing with some buggy behavior in an API — where that buggy behavior doesn't spit out any distinctive error message to use in the search.
I could see ChatGPT being good at a limited version of this problem, where I could give it e.g. several definitions of a word (= correlated keywords), and it could tell me the word that fits those definitions.
But the full version of the problem — pointing you at (or regurgitating) the one unique conversation that most highly correlates with your keyword cloud — essentially implies an Internet-scale "language model": one where there are unique vertices for every unique URL. Which, if you think about it, is what a traditional search engine's index is: a very dumb, but very large correlational language model, where that "dumbness" is a valuable constraint meaning that queries are able to be run map-reduced across many nodes.
Is there something I'm missing here, that makes Bing+ChatGPT better at these types of queries than Google is?
Or are the advantages ChatGPT is bringing to the table here, in areas that have nothing to do with making search engines better at the things they're already "the best tool for the job" at, and instead are in solving problems that could be solved any number of other ways (e.g. querying a search assistant such as Siri/Alexa; or pulling up an encyclopedia article or textbook relevant to the subject and just reading it) such that a search engine wouldn't necessarily be the first tool you'd search for?
