You can also easily have Objective-C, C, and C++ in the same Swift project and have them interop. That’s a feature of Swift. But adding their numbers together wouldn’t make sense.

Doesn't really bring benefit. With Java you are more quickly useful in C++ and can write server apps without fuss. Very little benefit in using a different language when Java literally does the same and is used everywhere else.
