I'll give you a very simple example I saw recently. I saw a dad joke in Spanish on social media and it gave me a chuckle. It was a comment to a lawyer's video and it translates to "can I study law if I'm a leftie?" It relies on the fact that law is also a word for "right".

AI won't be able to succinctly translate that joke and have it hit the same way. As an experiment I just fed that into ChatGPT, and it did explain the pun in 6 paragraphs with quotations and a bulleted list, but that kills the simplicity of the humor.

It can't now. It will be able to in the future, when the translation actually becomes fluent for the user.
