What's the difference? I'm still not actually sure where R sits these days but it is certainly my impression its confined to an ever smaller niche of social scientists and non-CSy folks. As more and more fields becme programmer-native, that niche becomes naturally smaller. Most, if not all, quantitativepy trained students now (and have been for a while) are bilingual in Python for glue and analysis and C++ for compute. R is also not a great fit for HPC, at least, they people attempting it are as few and far between as Windows supercomputers these days.
Rstudio is arguably Spyder, and they seem well positioned to blow it away if they let go of R.
I've worked with a few numerical fields now (physics, medicine and neuroscience, some of the largest consumers of academic HPC) and I can count the number of R folks without hands. Even friends at consulting firms and fintech, and they're also not using R. Or am I missing something?
