At best it means that the AI shapes our civilization into some sort of twisted extrapolation of what other alien races might like. In the worst case, it ends up calculating a high probability of existence for Evil Abhorrent Alien Race #176 which is in every way antithetical to the human race, and the acausal trade that it makes is that it wipes out the human race (satisfying #176's desires) so that if the #176 make an AI, that AI will wipe out their race as well (satisfying human desires, since you wouldn't believe the terrible, inhuman monstrous things those #176s were up to).
