Rust is better than Go for sure (cough Generics) but it's already hard enough to fight the mathematics, statistics and machine learning, scientists will not want to fight the Rust syntax as well.

For me, the most promising compiled and statically-typed language for scientific computing is Nim.

Disclaimer: I am the author of a Numpy/Torch/Tensorflow-like library written from scratch in pure Nim, the look and feel is pretty similar to Python Pytorch + Keras for neural networks: https://github.com/mratsim/Arraymancer
