Surely, running an AI with a rock permanently on the keyboard is functionally equivalent to not running an AI? Why spend computer cycles on running an AI that you're not going to interact with? Why create the AI and put it in a box in the first place, if you've committed yourself to leaving a rock on a keyboard? (This would be the first point I'd make to a rock, were I a boxed AI.)

I'm still a neophyte here, but I admit I was fascinated by the two AI victories I heard about some time ago, and intrigued further by the losses (which if nothing else provides some support against the theory of some reliable clever trick).

Out of curiosity, is there a citation somewhere for the three other games that were played, with documentation of the participants, stakes, and AI/Gatekeeper defeat statements?
