PHYSIX OBSERVATION

Nvidia is stuffing the full CUDA stack into Windows laptops, turning local large models from a developer toy into an office standard. Microsoft is locking down agents with MXC, and in doing so it is grabbing operating-system dominance for the AI era. For users, it is a win for privacy and latency; for cloud providers, it is the first crack in their compute business as workloads get diverted.
