But even if Intel have stable optimized drivers and ML support, it'd still need to be supported by PyTorch/etc for most developers to want to use it. People want to write at high level, not at CUDA-type level.
I just tried googling for Intel's PyTorch, and it's clear as mud as to exactly what's run on the GPU and what is not. I assume they'd be bragging about it if this ran everything on their GPU the same as it would on NVDIA, so I'm guessing it just accelerates some operations.
