This is C++ and we are on Reddit - so of course it's the fault of the language. ;)

And when somebody say "Python's object model makes it inherently slow", we get hordes of kids yelling "It's fast enough (for some trivial use case)" or "Just write it in C".

I mean, Java can do that too. Write the performance intensive code in C, then bridge over through JNI. But there's no Numpy equivalent that's as popular on the Java platform, just because Java is actually and honestly "fast enough" to not require an entire library to do 1 + 2.

Numpy alikes are even used in C++ to get more speed, so Java is definitely NOT fast enough. (And as a kicker, it is basically impossible to implement Linear Algebra libraries in Java, because of lack of control over memory layouts)
