I think your productivity in Scala would be quite a bit higher than in Rust. I've done reasonable amounts of Rust and quite a lot of Scala, and _given the current state_ Rust is simply slower to develop in. C++, well, you know what the downsides there are if you prefer it over Python. I think for a particular data science mindset (the category theory toting, bijection loving person) Scala actually _is_ essential to the work of data science. But these people are in a minority. Anyway, if you're truly in the second category, then the fact that the best library for doing X is in Scala would mean you're going to write some Scala, despite the fact that it's ~accidental that it was written in that vs Python.
