For me that’s its most promising feature. At last a truly cross platform compute library (not this, WebGPU itself). With two complete and mature implementations no less (dawn and wgpu).
WebGPU is interesting outside the browser: both dawn and wgpu-rs can be used as cross playform native gpu layer. That does not depend on firefox having webgpu support
I've had hour long conversations explaining the project talking about how webgpu can be used natively, how rust and zig people are using webgpu as a main GPU APIs (with wgpu and mach) and at the end there's still clarification questions about differences from WebGL and WASM.
The phrase "native webgpu" might as well be a Stroop Effect prank in technology branding.
