Only if you are in those respective ecosystems. I write embedded code so I don't get any of those options. Most of my code is in C++ because historically that is what we knew best (we have been updating to modern C++, so it is one of the better C++ code bases, but still it has the warts of C++). Integrating anything other than C++ into our code is hard. Many things are a class, most with virtual functions (London vs Detroit mocking is a different rant), and nothing except C++ really knows how to deal with it. Then there are templates - std::vector is the perfect type for so many things, but again nothing else can deal with it.

I keep trying to figure out how to use something else, but it is really hard to break in. Those who have tried before me gave up because of the friction.
