I exclude Khronos because at least they're able to put aside industry politics to deploy an open API. The problem is the rest of the industry - even if there was a good alternative, nobody would use it. Microsoft has DirectML™, Apple has Accelerate™, and Google has a few thousand tensor accelerators they don't know what to do with.

Everyone is out for blood in this market. Going after Khronos for not addressing Fortran FFI is a cart before the horse argument, from where I'm standing.
