I decided to see how ChatGPT could do against the assignments by writing Python in my university deep learning course. It completed 4 of 10 perfectly, and tripped up on the others.
Neither rosetta stone nor "hello world" implies anything about "universal". Actually, quite the opposite. The real Rosetta stone is a very small subset of the 3 languages, but paved the way for greater understanding. The real Rosetta stone text is actually pretty mundane. And "hello world" apps are anything but "universal". This is just how to do a simple (non universal) data science task in 5 languages.
