Though my knowledge of physics is near nonexistent, I imagine future AIs wouldn’t inspect each other’s source code; they would instead agree to set up a similar tournament and use some sort of inviolable physical prohibitions in place of tournament rules. This sounds like an exciting idea for someone’s future post: physical models of PD with light, gravity etc., and mechanisms to enforce cooperation in those models (if there are any).
