>> Is rust suitable for data science workflows? >> Right now I have to say that the answer is “not yet”. I’ll definitely reach for rust in the future when I need to write optimized low-level code with minimal dependencies. However using it as a full replacement for python or C++ will require a more stabilized and well-developed ecosystem of packages.

I'm not sure rust is really aiming to be something used for data science workflows. I'm not sure the community will be putting much effort into making this a reality.
