Yeah I mean you are preaching to the choir there. I picked up a used 3090 because rocm on the 7900 was in such a poor state.
That being said, much of what you describe is just software obstinacy. AMD (for example) has had hardware encoding since early 2012, with the 7970. Intel quicksync has long been a standard on laptops. It’s just a few stupid propriety bits that never bothered to support it.
CUDA is indeed extremely entrenched in some areas, like anything involving PyTorch or Blender’s engines. But there’s no reason (say) Plex shouldn’t support AMD, or older editing programs that use OpenGL anyway.






CUDA is actually pretty cool, especially in the early days when there was nothing like it. And Intel/AMD attempts at alternatives have been as mixed as their corporate dysfunction.
And Nvidia has long has a focus on other spaces, like VR, AR, dataset generation, robotics, “virtual worlds” and such. If every single LLM thing disappeared overnight in a puff of smoke, they’d be fine; a lot of their efforts would transition to other spaces.
Not that I’m an apologist for them being total jerks, but I don’t want to act like CUDA isn’t useful, either.
