I have a draft blog post up about Apple's recent Metal shader converter tool: https://github.com/raphlinus/raphlinus.github.io/blob/ec87e0bd22ea848e3ed8bb3d37930a1ef7750d3c/_posts/2023-06-08-shader-converter.md

Basically, I feel it furthers fragmentation of the ecosystem, and fails to make progress toward a solid foundation for GPU compute. I also make the case for #WGSL and #WebGPU by comparison.

Comments and suggestions are welcome!
