Bioinformatics is also seeing huge gains from rewriting the slow Python code into highly parallel Rust (way less fiddly than C++ for the typical academic dev).

This is not new either. Most of numpy and pandas and other stuff you use the Python C interface and pass arrays in and get data back. You can write small embeddable C libraries pretty easily for real crunching and you get the ease of writing python (basically comprehensible to researchers who understand The MATLAB )
