"Viable" in scare quotes, as it should be. Note that the third one you listed is forked from the second one with licensing credit stripped. None of them are actually used by anybody programming anything real. Calling this commoditization is ridiculous. Commoditization of being able to post superficially impressive claims that get upvoted to the front of HN while drowning out content that has >0 value to anyone on the planet, I suppose.

I'll note that I _am_ also dubious of the lifespan / long term viability of these projects (easy come, easy go), and I agree that they're very rough / early stages right now. That being said, I'm not writing off their value either. I've played with all of them, and while they aren't bulletproof (I haven't managed to get Bevy to actually run with any of them), they are undeniably close to being viable.
