"I feel like having a more common language would just lead people to bang their heads against the impossible or implement horribly inefficient algos not really understanding what's going on under the hood"

I completely disagree. The author is not really arguing for a "more common language" anyhow - he's arguing for a GPU language that avoids many of the inefficiencies and semantic problems with the current approach. To boot, he's arguing for an approach that allows better static error checking, which it's hard to argue against.

I have to say it's sad that Apple went with Metal rather than working to evolve Vulkan as an excellent standard. We'll see how that works out in the long run...
