The idea that CUDA is the main reason behind Nvidia dominance seems strange to me. If most of the money is coming from Facebook and Microsoft they have their own teams writing code at a lower level than CUDA anyway. Even deepseek was writing stuff lower than that.

Its not efficient to write low level code. Its like trying to build a web application with C.

CUDA is basically the equivalent of "hey you wanna do matrix multiply fast? just use this and we handle the rest". And its standardized, and when Nvidia comes out with new cards, all the old shit still works.

What is lower than CUDA? Compute shaders?
