Is it really that short? This support matrix shows ROCm 7.2.1 supporting quite old generations of GPUs, going back at least five or six years. I consider longevity important, too, but if they're actively supporting stuff released in 2020 (CDNA), I can't fault them too much. With open drivers on Linux, where all the real AI work is happening, I feel like this is a better longevity story than nvidia...where you're dependent on nvidia for kernel drivers in addition to CUDA.
