The full ChatGPT does that for "the internet" as it was on training time (2021). One of its disadvantages/challenges for information retrieval tasks is that its knowledge cannot be updated easily (perhaps soon to be more or less resolved), and that it's unclear how it has gathered the specific knowledge it is presenting.
Regarding the updating part, it still needs an automated way to discover new sources which leads back to internet crawling and hence one of the most costly parts of current search engines.
