With an evolutionary approach, the basis of morality can be explained as adaptations to for example problems of cooperation. With ‘evolution’ taken in a broad sense, reproducing AIs that satisfy the conditions for evolution to apply will be subject to the same cooperative evolutionary pressure as biological entities. Here the possibility is discussed that the predisposition to cooperation, together with diminishing beneficial returns from increasing access to material resources, predicts increasing cooperation as material safety and wealth increase — for humans, for other societies, and for AIs. This, along with data of human progression, suggests a projection that humans will become more and more cooperative and considerate. It also suggests the possibility that, on the whole, there will be no incentive to for instance colonize entire galaxies, thus providing a possible explanation of the Fermi paradox, wondering where everybody is. It is further argued that it is likely that old societies engender, give way to, super-AIs, since it is likely that super-AIs are feasible, and fitter (where ‘old societies’ here means societies that have undergone more biological and cultural evolutionary changes than human society). Appended are an algorithm for colonizing for example a galaxy quickly, and models of the evolution of cooperation and fairness under diminishing returns.
