If you're like me you want to write code that runs on the GPU but you don't, because everything about programming GPUs is pain. That's the use-case I see for rust-gpu. Make CPU devs into GPU devs with an acceptable performance penalty. If you're already a GPU programmer and know cuda/vulkan/metal/dx inside out then something like this will not be interesting to you.

I'd much rather glue my inline PTX together with Rust than CUDA C++.
