Have we really changed all that much?

I am starting a class on computer network security. We humans have invent radical new technologies. But while our technology has advanced, we haven't changed. We just have better technology to do evil with. We are learning of the dangers of "social engineering". That just a fancy name for what we used to call lying. And network attacks are just another form of stealing. If we kept the ten commandments, we wouldn't need firewalls and virus scanners on our computers. My teacher is a bit of an expert in the dangers of cyberwarfare and terrorism. She teaches a class on it. Some day we could use all this technology to literally kill each other. What she is telling is very scary. We humans are smart but are we wise? Maybe we need Someone far wiser than us to fix us.
