Depends on your use case - if you are coding, or doing constraint analysis - 75+% of the time it's a single request, single answer, and you are done. The other element with ChatGPT is if you aren't happy with the initial answer for some reason - you can engage in a conversation with it, provide some guidance, and will adjust it to suit
specifically what you are interested in. I've found about 50% of my google searches just go straight to ChatGPT these days. Hallucinations are the only real problem I've had - but over time you start to become cynical about the truth of anything factual - asking for unit tests helps quite a bit when coding - double checking any math is also important.
I do agree though, that without citations to the original source - any "Facts" that ChatGPT offers are absolutely untrustworthy.
