CUDA is not just a programming API but a layered, highly‑tuned software ecosystem that makes GPUs into a platform, preserving Nvidia's market power by forcing ML stacks to target its hardware. Deep, hand‑tuned libraries and even PTX‑level optimizations create switching costs larger than raw silicon performance differences.
— If software stacks, not just chips, determine who wins AI, policy and competition debates must shift from fabs and tariffs to platform ecosystems and developer tooling.

AMD's public hiring and LinkedIn signals about embedding Rust 'deep into the GPU stack' (firmware, compilers, drivers, tooling) is a direct counterpoint to the ecosystem of vendor‑specific stacks like CUDA: it may reshape which vendor toolchains and languages dominate GPU compute and thus reconfigure platform lock‑in dynamics; the article also notes NVIDIA pursuing Rust initiatives (Nova driver), making this a multi‑vendor movement that affects the same lock‑in problem the existing idea addresses.
