Dennis Gorelik, a Senior Developer at IBM and creator of the PCnous artificial intelligence system, identifies a weakness of an AIS (artificial intelligence society, consisting of computers trained to 'think'), in that it was not born through natural selection, as human beings are. However, one could view whether this is a disadvantage or an advantage from a couple of sides. Within human natural selection, there are biases based on upbringing, genetic factors, and how ultimately one responds to.
