Is there anything fundamentally superior about Cuda over open CL?
Yes: market share. And Nvidia has the top performing cards on the market, so there's no reason to go with a competitor.
And inertia. Same reason x86/64 is still the king. Nobody wants to update their software to a new architecture
Exactly. People will do it if there's a big enough incentive, but that just doesn't exist for openCL.
I am not an AI programmer so I can't really say. But CUDA had a head start and was some years ago allegedly the best combo with Nvidia hardware for AI programming. Over a period of time a lot of companies/projects have come to use CUDA, and so it has an advantage both for compatibility and know how among many AI programmers.
It's kind of like how X86 has maintained a market lead on desktops and servers, despite ARM being very competitive. The change of API is disruptive and costly, so people stay with what already works.
