This ecosystem lock-in means any competitor faces the equivalent of trying to build an iPhone competitor without the iOS App Store ecosystem, making displacement structurally hard. The implied catalyst is continued AI compute demand flowing to Nvidia rather than rivals; no explicit time horizon or risk is stated.", "thesis_short": "CUDA ecosystem lock-in protects Nvidia from rivals", "quote": "Its install base. all of their stuff is designed to run primarily on Cuda.
