@Bronwyn Yes, when discussing history with people, I usually point out that all kinds of things change, scenarios are different, every imaginable thing might happen, but one thing that never changes is human nature. You can depend on this. The way people were in Roman times, in Greek times, in Egyptian times. in ancient Chinese times, is the same as today.
Humans need to evolve at least one more step before we can have a "Star Trek" kind of society. We're still too brutal, too selfish.
@shuttersparks the more things change, the more they stay the same
