Actually, as I read more about it and watch more videos about it, it seems like that isn't necessarily true. The claims they have at the top end surpass what any chassis platform I've seen is capable of, though I don't know that they actually have pushed the upper bounds of what's possible in the real world.
I wonder how large a failure domain folk are willing to accept.
I also don't know that it's actually better to have 1 thing vs N things, since management of the
things is probably the expensive part (once you get past space/power which don't seem to be
part of the calculations here (not in my brief read of the thread at least).
