I would not use C++ in your comparison. Try with C# or Java. Not even close. They will crush in developer productivity and maintenance over Python, Ruby, Perl, JavaScript.
Developer productivity in these scripting languages is also even higher. Simply because of how much faster they are to program in with the code then run/test loop. Java and C# can have loong compile times. Python and typescript are typically much much more quicker. With the additional type safety python and typescript are actually categorically higher in developer productivity then C# or Java.
But that's besides my point. Let's assume we aren't using modern conventions and javascript and python are typeless. My point is that whether or not C# or java crushes python and javascript over maintenance it doesn't win because of type checking.
I work with C++ currently. Even the incremental build is too slow. Also eventually you have to clear the cache for various reasons including debugging, a new library, etc, etc/
1M line python is 0s compilation time. You hit the runtime section instantaneously.
Go was created with fast compilation times to get around this problem. I would say in terms of compilation, go basically is the closest in terms of the python experience.
Basically when things are fast enough "5x compilation time" isn't even thought about because things are too fast to matter anyway. Go hits this area as well as python (given no compilation)
