For me, the calculus is simple: is the platform maker ensuring their work is merged upstream? If not, what’s the point? The field moves way too fast to rely on

For me, the calculus is simple: is the platform maker ensuring their work is merged upstream? If not, what’s the point? The field moves way too fast to rely on forks. Relying on Intel’s comparatively unmaintained PyTorch fork (stuck on PyTorch 1.10) is foolish. Hell, Apple, despite their reputation, has done a better job working with the PyTorch organization than Intel.
