It has limitations for sure. I asked it some questions about an API and it told me it had a specific capability, which I didn't think it had. Then I asked it how it knew that and it gave me an URL to docs and a quote. While the URL existed, the quote from that page didn't, and it never did exist (I checked.) It was incredibly strange to see it confidently tell me things that were clearly statistical extrapolations.

So yeah, ChatGPT is awesome, but it doesn't differentiate reality from its statistical extrapolations.

I think there has to be a way to possibly add a module on top that somehow is trained to identify reality-based content and when it is making up likely scenarios. Humans are capable of both of these modes but we differentiate between them. ChatGPT is capable of both of these modes, just doesn't have the differentiator yet.
