It's kind of hilarious to be saying that Apple is more likely to be seeing traction on Metal of all things, when all but the last one of those requirements fit graphics programmers in Vulkan or DirectX, both of which have far more traction than Metal, and that last requirement is pretty easy to pick up if you're an expert in linear algebra and calculus.
It gets even stranger when considering that as major GPU makers, both AMD and Intel have lots of access to such talent.
Vulkan only has traction on Android, and a couple of Linux titles.
Metal has 20% of the desktop market, and whole of the iOS/iPad/watchOS markets combined.
Even with Android market share, many folks keep using OpenGL ES, because Vulkan tooling on Android sucks and isn't available to Java/Kotlin developers like OpenGL ES is, so only game engines like Godot/Unreal/Unity make use of Vulkan in practice.
