There is in fact artificial general intelligence and emotions, desires, etc, in computer worlds: 1) multiplayer games with "bots" 2) all these things, on a lower level, serve to make groups of entities communicate and cooperate. Even in solitary animals like cats these emotions serve to facilitate cooperation, to produce offspring or share territory optimally. There is no problem with creating that artificially: just have multiplayer environments with multiple artificial entities cooperating, resource constraints, "happiness", "pain" and "sorrow". It's going to take a while before we see these entities compose poetry when their mate dies, but it'll go in the same direction.
