Oddly enough, yes. Don't judge; nerds come in all types.

You don't need a lot of depth of knowledge to know when a culture completely changed. If you go outside and see a Toyota Camry and another Toyota Camry a week later, you can't tell whether the car is the same one. On the other hand, if one day, it's a Porsche, and the next week, and 18-wheeler, you can be pretty sure something changed....
