What suprised me most about the real Gordon Selfridge was actually about his sons, Ralph and Oliver. They were both highly respected in their fields, influencing Information Technology and Robotics deeply. Oliver Selfridge has even been referred to as 'The Father of Machine Perception,' being a pioneer in Artificial Intelligence.
I'm more frightened than interested by artificial intelligence - in fact, perhaps fright and interest are not far away from one another. Things can become real in your mind, you can be tricked, and you believe things you wouldn't ordinarily. A world run by automatons doesn't seem completely unrealistic any more. It's a bit chilling.
