What is the state of WASI vs. emscripten? I have tried wasmtime (which downloaded more than 400 crates to build) with wasi-libc, only to hit this issue:
https://github.com/bytecodealliance/wasmtime/issues/8068
With emscripten, which can package the required files instead of accessing the file system. everything just worked.
But emscripten is occasionally described as "unmaintained".

There's no reason? Are you sure about this?
I think you mean there could theoretically be an interpreted Rust, but I don't think anyone has ever made a prototype of a Rust interpreter.
The closest is probably rust-analyzer (the official language server), that maintains internal state and reacts to changes you make, but it doesn't create an executable artifact.
The other is probably the Cranelift Backend (https://github.com/rust-lang/rustc_codegen_cranelift), which can produce debug builds quickly.

Project mention: CubeCL: GPU Kernels in Rust for CUDA, ROCm, and WGPU | news.ycombinator.com | 2025-04-23
Agreed! I was looking through the summation example < https://github.com/tracel-ai/cubecl/blob/main/examples/sum_t...> and it seems like the primary focus is on the more traditional pre-2018 GPU programming without explicit warp-level operations, asynchrony, atomics, barriers, or countless tensor-core operations.
The project feels very nice and it would be great to have more notes in the README on the excluded functionality to better scope its applicability in more advanced GPGPU scenarios.
