Decades of dedicated human time, teams of humans, etc. are all forms of super-humanity.

Only in an extremely weak sense. Humans can do and think things that cats just can't, even if they think for a long, long time, or have a bunch of cats working together. The power of a truly superhuman intellect is hard to imagine, and easily underestimated.

In any case, the drafter of the rules would have an enormous comparative advantage, because he can unilaterally enforce dictates on the other party, while the other party has no such authority. It's not guaranteed he'll cover all the angles within the human domain, but it's at least possible, unlike in the case of an AI, where such a strategy is basically guaranteed to fail.
