> WebGPU is at least one year away of becoming usable for cross browser deployment.
In Firefox it seems to be behind a feature flag and Safari seems to have it in it's "Technology Preview" (some sort of release candidate?), so seems closer that I at least though.
Firefox has had it as feature flag for at least one year now, Safari just announced the technology preview during WWDC updates.
WebGL 2.0 took almost a decade to be fully supported, and still has issues on Safari, don't expect WebGPU to be any faster.
Also note that Google is the culprit why WebGL Compute did not happen, WebGPU was going to sort all problems, and even though they use DirectX on Windows, apparently it was a big issue to use Metal Compute on Apple instead of OpenGL, and then they ended up improving Angle on top of Metal anyway.
