If it's citing all it's sources, it's not ChatGPT, it's a natural language interface around search, which Google has been doing for years including with voice...
"Get answers instead of being overwhelmed by options. Bing looks at search results across the web and summarizes responses to your specific questions and needs."
There's summarised cited searches and then there is the more ChatGPT option which is also available.
Presumably they have bolted on something that cites sources. This doesn't mean that the things ChatGPT says are true, just that you can check some sources that are plausibly relevant.
Traditional search practically forces you to read the sources directly. With ChatGPT, people will just assume its citation is correct due to laziness.
I've seen this with many human published articles on the Internet too. The litany of citations fool everyone into thinking that the article is credible, but when I actually read the citations, they don't support the article at all.
