Sorry if this sounds ignorant, but does SPIR-V count for nothing?

Overthrowing may be hopeless, but I feel we should at least be a 
really competitive with them.
Because it doesn't matter whether we're competing with C++ or 
not, people will compare us with it since that's the other choice 
when people will want to write extremely performant GPU code(if 
they care about ease of setup and productivity and _not_ 
performance-at-any-cost, Julia and Python have beat us to it :-(
