Jensen Huang, reasonably, was desperate for any market that could suck up more compute, which he could pivot to from GPUs for gaming when gaming saturated its ability to use compute. Screen resolutions and visible polygons and texture maps only demand so much compute; it's an S-curve like everything else. So from a marketing/market-development and capital investment perspective I do think he deserves credit. Certainly the Intel guys struggled to similarly recognize it (and to execute even on plain GPUs.)
But... the technical/academic insight of the CUDA/GPU vision in my view came from Ian Buck's "Brook" PhD thesis at Stanford under Pat Hanrahan (Pixar+Tableau co-founder, Turing Award Winner) and Ian promptly took it to Nvidia where it was commercialized under Jensen.
For a good telling of this under-told story, see one of Hanrahan's lectures at MIT: https://www.youtube.com/watch?v=Dk4fvqaOqv4
