Ex-Nvidia CUDA engineer: 'CUDA is not the moat — Nvidia's only moat is its people'
AlpinDale · x · 2026-11-13
An engineer who spent eight years on CUDA compilers, libraries, and DSLs (Volta to Rubin) argues the common belief that "CUDA is NVIDIA's moat" is naive. NVIDIA's only true moat is its people — above all Jensen Huang.
He contends CUDA is far more than a language plus compiler with software lock-in: "CUDA is everything NVIDIA does" — a product defined by a unique customer experience. The thread continues from an insider's perspective.
