Anthropic makes claude, claude can write Rust like a champ and struggles at Zig. It's a straightforward "training data" argument.

I think there are even longer term plays that Anthropic should be looking at, in this space, but it seems like they've decided rust is the right thing, so fair play. I would be (am!) thinking about making an LLM optimized high level language that you can generate / train on intensively because you control the language spec.

Claude doesn’t write Rust like a champ. It’s still miles ahead at js and python than it is at rust. It can do macros and single file optimizations but its gotten really stuck in type hell and tried to dyn everything on multiple occasions for me.

Claude struggling at Rust: not getting types correct, using the wrong abstractions, not implementing things correctly

Claude struggling at Zig: the above + memory safety issues if you run “fast” mode.

It is generally true that Rust code tends to be written in a way that the compiler catches the issue at compile time. The same is not as true for Zig, Python or JS

As a human occasionally writing Rust I've also frequently got stuck in type hell.

claude does not struggle with zig? not in my hands anyways.
