Well right now I'm very fascinated with 1920s Berlin. I mean probably the more interesting thing would be to go to the beginning of civilization or precivilization - like polytheistic times. It would be interesting to see what came before modern religion and culture - what circumstances created the environment or the need for it.
So I see technology as a Trojan Horse: It looks like a wonderful thing but they are going to regret introducing it into the schools because it simply can't be controlled.
