Ah right, I should have been more specific. I didn't realize the Jupyter name was a combination of programming language names, but I did know about kernels.
For some reason the non-Python kernels always felt like second class citizens, but I think that might have been because there were other notebooks for languages like R and Scala, and in those notebooks the language integration felt more natural.
Well, Python is privileged in that you have to install it to run the notebook. But when you are using the notebook, all the languages are the same; there’s nothing Pythony about it.
