>> Either you port Tensorflow (Apple)[1] or PyTorch to your platform or you allow CUDA to run on your hardware (AMD) [2]. Companies are incentives to not have NVIDIA having a monopoly but the thing is that CUDA is a huge moat due to compatibility of all frameworks and everyone knows it. Also, all of the cloud or on premises providers use NVIDIA regardless.
This never made sense to me -- Apple could easily hire top talent to write Apple Silicon bindings for these popular libraries. I work at a creative ad agency, we have tons of high end apple devices yet the neural cores sit unused most of the time.
