This is nonsense. To combine AI systems requires a mechanism to combine their evaluations. The most effect way would be a feedback system, where each system uses evaluations from other systems as input to possibly modify its own evaluation, with the goal being consensus. This is simply a formalization of argumentation -- which can be rational; it doesn't have to be based on personal benefit. And generalized AI systems may well some day have personal motivations, as has been discussed at length.
