And yet current versions of Whisper GPU will not run on my not-quite-10-year old Pascal GPU anymore because the hardware CUDA version is too old.

Just because it's still called CUDA doesn't mean it's portable over a not-that-long of a timeframe.

Portable doesn't normally mean that it runs on arbitrarily old hardware. CUDA was never portable, it only runs on Nvidia hardware. The question is whether old versions of Whisper GPU run on newer hardware, that'd be backwards compatibility.
