Everybody wants to use evolutionary mechanisms in new media. There are folks who program little AI bots and let them evolve. I feel this is misguided in that a pre-programmed AI is never going to mutate the way a real entity would. Automata are never going to come up with molotov cocktails and IEDs. A virtual world, I've argued, is the best way to get the emergent/evolutionary thing going: replace the programmed automata with people. You'll get plenty of little nasties you never anticipated.
Now, Spore was supposed to give us an an example of how much better this strategy would be. In Spore, real people were going to make creatures that would survive or die out. But the Spore we eventually got doesn't do that, Science reports. Basically, Spore sucks. They didn't make a virtual world in which everybody's animals had to survive in competition over scarce resources. They made a toy.
OK. So look, just make a virtual world with the people as the entities. You'll get evolution.
