So in other words, Java is bad at scaling a basic math operation like multiplication?

The AI-space is proof positive of that being false. C++ is kicking Java's butt, squeezing literally trillions of ops per second of performance, all of this happening before the Java runtime can even startup.
The first transformer-based language model was built with PyTorth; imagine if PyTorch was a python wrapper for Java code instead of C++ code? It'd be garbage. I mean how freaking long did it take for Java to even get a basic Vector API? C++ devs have been writing SIMD optimized code for years now. And besides that, try getting a Java program to scale at tens or even hundreds or thousands of GPUs for a large language model. You'd need GPUs with literally 20-30% more RAM just to accommodate the GC.
