Nice that ChatGPT does that, its also true that Google Translate and other APPs have had this functionality for a decade or more. I was getting live German translated on my phone in 2015 with no problems.
I have been using google lens heavily to scan posters/flyers/information displays in other languages and get it translated to english in like 2-3 seconds. So freakin helpful.
Google translate was not very good, it didn't get context. Deepl was better
Yes, there have been translation apps for along time, but the LLMs are much better. If the phrases can have dual meanings the LLMs will often explain so you end up with a better understanding of what was said/needs to be said. The LLMs can pull more context from the web, so if you're dealing with more complex topics that may have acronyms they are much better at getting to a correct translation.
