Simd: ETA for GA date?

[unicomp21]

Given Webassembly/simd is taking so long, perhaps it's not meant to be? Should we just cancel the whole thing?

WebAssembly SIMD is available in Chrome (under Origin Trial, or with --enable-features=WebAssemblySimd flag), FireFox Nightly (no experimental flags needed), and several non-browser engines. There are products using it (TensorFlow.js, Google Meet). So I don't understand what your complaint is about.

Why do I have to get a token? Is there a lack of confidence in the current
implementation?

I do not work on Chrome, but my understanding is that Origin Trial is being used for web standards that are still being developed and promise no backward compatibility with previous versions of their specifications. As the specifications change, developers need to update their web apps, and Origin Trial motivates developers to update their usage of the web standard to the up-to-date specs because the token expires in 6 weeks and needs to be renewed.

Got it.

No. Feature flags and processes like this are useful to make users aware
of the potential for changes until the spec becomes a W3C standard.
