First off python now has types (you can place type annotations on the interpreter and run an external type checker) and javascript people use typescript. In terms of type safety i would argue python and javascript are now EQUAL to C# and Java. 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.

All of them could do initial compile with top spec desktop PC in less than 5 mins. Incremental builds were just a few seconds. If your incremental build in Java or C# isn't a few seconds, then your build is broken. Example: Apache Maven multi-module builds are notoriously slow. Most projects don't really need modules, but someone years ago thought it was a good idea. Removing modules can improve compile time by 5x. I have seen it with my own eyes.

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)
