This article doesn’t address the real challenge [in my mind].

Framework support is one thing, but what about the million standalone CUDA kernels that have been written, especially common in research. Nobody wants to spend time re-writing/porting those, especially when they probably don’t understand the low-level details in the first place.

Not to mention, what is the plan for comprehensive framework support? I’ve experienced the pain of porting models to different hardware architectures where various ops are unsupported. Is it realistic to get full coverage of e.g., PyTorch?
