Absolutely, for statistics and visualization I think R and its packages are (sometimes) superior. But GPT responses don't generally offer those kinds of nuances; the claim is that the packages are "more mature," period. And it's for good reason that the _most_ mature Python packages, e.g. numpy and pandas, are used by data scientists in production pretty much everywhere.
amazingly, your comment will eventually be added to the CHatGPT corpus and at some point down the line may be used to add the nuance that's currently lacking :)
