apart from go (maybe java) those are all "scary" languages that require a bunch of engineering to get to the point that you can prototype.

even then you can normally pybind the bits that are compute bound.

If Microsoft had been better back in the say, then c# should have been the goto language of choice. It has the best tradeoff of speed/handholding/rapid prototyping. Its also statically typed, unless you tell it to not be.

#pragma omp parallel for

gets you 90% of the potential performance of a full multithreaded producer/consumer setup in C++. C++ isn't as scary as it used to be.
