I've been coming to the opinion that I'll just never be happy with nominal static typing for data science or engineering. I'm curious about structural typing, but, of the languages I've tried so far, only dynamic typing has kept me happy for the long run.

I say that as someone who, prior to getting into the data space, was a fanatical partisan of static typing.

For actually implementing the core bits of analytics and ML tooling, I have a hard time seeing past languages that can match the performance of Fortran/C/etc and are able to expose a C ABI. Because those languages let you write one central, highly-optimized implementation that everyone can access from their favorite higher-level language.
