> Methodologically, how do we create agents that aren't just good at several tasks, but make up their own tasks, "play", develop changing preferences for different activities (I think this is more than just "exploration"), etc? Even a dog sometimes wants to play with a toy, sometimes wants to run and chase, sometimes wants to be warm inside. We don't "score" how well it plays with a toy, but we take its desire to play as a signs of greater intelligence than, e.g. a pet iguana which doesn't seem to have such a desire. This doesn't sound like it would be so hard to do if you have an agent or ensemble of agents that can already do it. What you probably really want is this behavior to somehow emerge from simple ground rules, which is probably a lot harder.
