A common theme that both Metal and CUDA share, which OpenCL ignored, is tooling.

Both embrace modern languages instead of plain old C, have very nice visual debuggers.

Also on Android side, Google is all about Renderscript not OpenCL.

OpenCL had to become an almost irrelevant, for Khronos to step up with SPIR and SYS-C++.

Yet they did it again with Vulkan, being plain old C.
