I agree with @BarryG. Even when considering that ChatGPT is nothing more than a lingual model, it still is very good able to translate questions that are not entered into the system on a structured way into a well-generated response.
Yes, it has it's perks. Yes, it depends on the data that was 'learned' into the system, but an incredible amount of data was input for the system. Therefor you get an anwer about an incredible amount of different subjects.
And for the 'AI'-name; in the contrary to systems where programmers program any amount of possibilities, these systems are programmed using an algoritm that uses 'learning-data' to build their dataset.
The system is not retrieving extra information from the Internet as I understood, what means that the system must contain an incredible amount of data. That also impresses me.
I also agree that 'intelligence' is debatable. But that also applies to a lot of people
