For a lot of what I do (large-scale, scientific computing), C++ is exactly what I need: it's expressive/compact when I need it to be, and its compile-time metaprogramming lets me do things faster in ways no other language can. For testing and interactive analysis, I can easily use pybind11 to generate bindings. And because python integration is so easy, I can know many other people will be able to use it. That's the balance I like best.
