"If" indeed. Apple has a trillion-dollar AI market staring themselves in the face, and they can't even find it in them to sign CUDA drivers for their own good.

The features you're describing would not buy them credibility in the AI field anyhow. They would certainly plaster over some of macOS and iOS' more embarrassing limitations, but professional AI deployments are not hamstrung by those limits. It's just the commodity homelabbers who want to brag about buying a 120gb GPU with anemic compute performance. Apple doesn't need to curry favor with those people, they'd buy the hardware for the luls regardless of what the software experience is like.
