Python isn't much better in this regard, thanks to the GIL.

What I actually found most baffling when I delved into R is the fact that it doesn't support 64bit integers (lack of proper native UTF-8 support coming a close second).

Take some standard ML model built with Caret or LME4 and try serve predictions with Plumber in R. It’s significantly more painful than using sklearn + FastAPI. You either need to use future::promise (which still sucks because it’s forking new R runtimes) or forgo this and go K8s or something similar.

I don’t get the love for RStudio either. It crashes frequently for me, or locks up randomly. The debugging experience is abysmal compared to PyCharm. Getting reproducible R builds are a pain, slightly alleviated by Renv. But not really if you want separate dependencies for dev and production.

Python and R tooling are not comparable. You will have serious issues operationalising R. Skills that most statisticians are simply not equipped to deal with, and serious software engineers will hate about R.

FWIW I have many years of full-time RStudio dev experience, and while I've definitely had a few hard-to-explain crashes, I'd characterize it as very reliable overall. When problems arise they tend to be due to community-contributed packages, especially packages that call out to C++. (My name is on the bug fix log for some major packages.)

Unintentional and unnecessary creation of huge, memory-hogging objects is a closely related footgun. Packages are often not built with large data in mind and make choices that scale terribly, such as storing multiple copies of the data in the model object, or creating enormous nonsparse matrices to represent the model term structure. It's a legacy of the academic statistics culture R grew out of. Most researchers test their fancy new method on a tiny dataset, write a paper, and call it a day.

No argument about the debugging experience. I find it very slow, especially with large datasets, and try to avoid it. Not much experience with reproducible R builds but I wouldn't be surprised if it was a pain.
