When I tell people that I'm a history major, the most common follow-up is, "and what do you plan to do with that?"
All people with a good knowledge of history have two options:
1. Create a crazy theory where the "progress of human history" will lead to some sort of utopia (or more rarely, a dystopia).
2. Look with a melancholy resignation on world events. (History people know what I'm talking about.)
I'm probably going to stick with option 2. Although our technology may have improved, our society has only "improved" past the Ancient Romans in a few areas, and has actually regressed in others. Unless some mutation in the human strain causes a real change in the course of events, we'll be no better in another 2,000 years.
The problem with the possibility of a "new" human arising from the current breed is that the current breed is optimized for one function: preventing the growth of things different from it.
