CUDA is the result of years of NVIDIA supporting the ecosystem, some people likes to complain because they bought hardware that was cheaper but can't use it for what they want to use it, when you buy NVIDIA, you aren't buying only the hardware, but the insane amount of work they have put into the ecosystem, the same goes for Intel, mkl and scikit-learn intelex aren't free to develop.

AMD has the hardware but the support for HPC is non-existent outside of the joke that is bliss and AOCL.

I really wish for more competitors to enter the market in HPC, but AMD has a shitload of work to do.
