CUDA is incredibly important still. It's still an incredible amount of work to get packages working on multiple GPU paradigms, and by default everyone still starts with CUDA.
The example I always give is FFT libraries - if you compare cuFFT to rocFFT. rocFFT only just released support for distributed transforms in December 2024, something you've been able to do since CUDA Toolkit v8.0, released in 2017. It's like this across the whole AMD toolkit, they're so far behind CUDA it's kind of laughable.
