> Superintelligence poses an existential threat to humanity

I disagree at least on this one. I don't see any scenario where superintelligence comes into existence, but is for some reason limited to a mediocrity that puts it in contention with humans. That equilibrium is very narrow, and there's no good reason to believe machine-intelligence would settle there. It's a vanishingly low chance event. It considerably changes the later 1-in-n part of your comment.

So you assume a superintelligence, so powerful it would see humans as we see ants, would not destroy our habitat for resources it could use for itself?

More fundamental than that, I assume that a superintelligence on that level wouldn't have resource-contention with humans at all.
