This is of course not "AI".
ChatGPT is simply able to answer in contextual human-like speech because it is piecing together sentences it sourced online.
This is also not new. Google has been adding answers to contextual questions for years. "How tall is the Eiffel Tower ?" is something Google has been able to answer for over a decade now.
The difference is that Google shows where they found this information. And the contextual data used so far has been limited to such an extent that it is still manageable for Google.
ChatGPT is just taking contextual answers to an extreme, and slicing and combining information from all over.
ChatGPT does not disclose where it found this information, how it found this information, and the date of this information.
A lot of data from ChatGPT is flat out wrong, outdated, or both. And while asking ChatGPT to write a poem is no big deal, people will be asking medical information, financial information, etc... and that's going to go horribly wrong.
