I just finished the Michael Chriton book Prey where man-made nanobots became nearly sentient and tried to take over the human race in a symbiotic way. They were programmed with swarm mentalities and given a very adaptive programming structure so that they learned from everything and since they were computers, they learned and 'evolved' to the point that they could coalesce into a realistic mimicry of humans.
I would be afraid, very afraid. BnM, stand fast, but if you start seeing Skynet on our forums, run.
And I thought Mafia games were tough. This takes the cake, even if the cake is a lie.
