That seems a bit harsh. Isn't WebGPU to WebGL what Vulkan is OpenGL? It's the next generation of more efficient 3D rendering pipeline.

Yes, but if you follow the discussions, the clear consensus was to use SPIR-V. Except Apple, who came up with all kinds of technical reasons not to use it, before eventually admitting they have a legal dispute with Khronos group. Now we get this weird language that is SPIR-V in text form but not by Khronos, and suddenly there is consensus.

Interesting, that's the first time I hear about it. Do you have some links on the topic? What is the essence of the dispute?

From the meeting notes [1]:
MS: Apple is not comfortable working under Khronos IP framework, because of dispute between Apple Legal & Khronos which is private. Can’t talk about the substance of this dispute. Can’t make any statement for Apple to agree to Khronos IP framework. So

@omar Note: WGSL ended up completely different than its initial proposed form and is no longer "SPIR-V in text form" and more like a conventional shading language.

@omar If I recall correctly, one of the main design constraints on that first version of WGSL was that it had to be bijective with SPIR-V (as a work-around for the Khronos/Apple IP issues) but that turned out to have too many issues.
