You get an answer.
If that's the answer, or even the best answer, is impossible to tell without doing the research you're trying to avoid.
If I do research, I get an answer. If that's the answer, or even the best answer, it's impossible to tell. When do I stop looking for the best answer?
If ChatGPT needs to, it will actually do the search for me and then collate the results.
By that logic, it's barely worth reading a newspaper or a book. You don't know if they're giving you accurate information without doing all the research you're trying to avoid.
Recognised newspapers will curate by hiring smart, knowledgeable reporters and funding them to get reliable information. Recognised books will be written by a reliably informed author, and reviewed by other reliably informed people. There are no recognised LLMs, and their method of working precludes reliability.
Malcolm Gladwell, Jonah Lehrer, Daniel Kahneman, Matthew Walker, Stephen Glass? The New York Times, featuring Judith Miller on the existence of WMD, or their award winning podcast "Caliphate"? (Award returned when it became known the whole thing was made up, in case you haven't heard of that one).
Not anymore, not for a long time. There are very few truly reliable and trustworthy sources these days. More and more "recognized" publications are using LLMs. If a "recognized" authority gives you LLM slop, that doesn't make it any more trustworthy.
