Please rewrite this in C++/Rust. Java at this point is a pure meme-tier language. I've dabbled with rewriting the JVM and actually properly optimizing but it's a complete waste of time when you can just generate optimal low-level code with inlined asm kernels where needed. You're genuinely leaving tons of performance/efficiency on the table. If you need a high performance minecraft engine there's TONS of rust rewrites on github, or you can generate your own.

Funnily enough, I have been dabbling at rebuilding this to work with this project: https://github.com/ludovic111/horizon

The only thing about rewriting it in rust is that no other mods will work with this and the thing that got me really excited about building this is using Create Aeronautics with it.
