I had similar experience; a friend use chatGPT to answer a question we had (was Stalin's son involved in the crash of an airplane carrying a Hockey team?). And it combined two separate events, a crash in 1953 which was actually the one we were thinking of, and another from 2011. It didn't give any sources, though I guess it may have been able to, but it was very confident in its answer and I only realised it was wrong because I was curious and wanted to find out more, but that certainly made me look at chatGPT differently. I don't think LLMs are in any way the replacement for search engines, certainly not in their current form.

Yes they are, though not in isolation. Additional mechanisms are needed to inject ground truth reliable knowledge into the LLM context. Don't ask an isolated LLM about facts and expect no hallucinations. Instead, use ChatGPT with search plug-in, Bing search, Perplexity.ai or Phind.com (Im sure there are others). Once reliable truth available to the LLM via context, hallucinations go down _significantly_ to the point where (to me at least) it's no longer really much of an issue.
