Genuine question, how does SPIR-V compare with CUDA? Why is SPIR-V in a trench coat less desirable? What is it about Metal that makes it SPIR-V in a trench coat (assuming that's what you meant)?

At this stage of the game what people want is CUDA. I just bought a new GPU and the only requirement I had was "must run reasonably modern CUDA".

There might be a subset of people, such as yourself, that looks for CUDA as a hard requirements when buying a GPU. But I think it's fair to say that Vulkan/Spir-V has a _lot_ of investment and momentum currently outside of the US AI bubble.

Valve is spending a lot of resources and AFAIK so are all the AI companies in the asian market.

There are plenty of people who wants an open-source alternative that breaks the monopoly that Nvidia has over CUDA.
