> huge for the progress of WASM

HUGE! 4x speedup for anything parallelizable. This should bring around ~45GFlops out of the box in the iPhone browser, which isn't much but easily enough for basic neural networks (think object tracking, background segmentation, face feature tracking). For comparison, WebGPU would get that to ~1000GFlops

This is huge for CPU workloads that need intermittent parallel processing.

A great example would be JSON parsing in WASM apps where SIMD algorithms result in massive speedups.

Another example would be a WASM software decoder could allow AV1 playback content on iOS browsers.
