It's not about finding similarities. It's about the basic way we live.
10,000 years ago people walked to where they worked, where they lived, where they shopped, and occasionally where they recreated.
500 years ago people rode horses or took wagons to where they worked, where they lived, where they shopped, and occasionally where they recreated.
Today we drive cars to where we worked, where we live, where we shop, and where we recreate.
Really, what's the difference? Our method of conveyance has improved increasing the range at which we can do these things but what has radically changed? Car, horse, foot, it's all just a method of transportation to allow us to get from point to another. All that technological advancement and all it's really accomplished is to increase how far we can go per unit time. We still use it for the same purpose. Heck, we still measure trips not by miles but by time. How long will it take us to get there? The only difference is how much distance we can cover per that unit time. Larger groups can now live together and interact making countries like the US possible but the US vs. a Grecian city state, what's the difference? One's just bigger.
However, the small things are still significant if you add them all together.
Wrong. The small things are static. They're background noise in the realm of human existence. I've grown up in the time where we went to each family had a telephone, probably on a cord, a TV, and a radio, to now when my own house has two TV's, a computer, a laptop, three tablets, and two phones neither of which has a cord and are each it's own mini-computer. And what's really changed? Not much. Massive technological revolution and our lives are still pretty much the same. The kids still watch cartoons on TV the only real change there is that a DVR means they watch what they want when they want. They still go and play with each other it's just that occasionally they get to play on a tablet. The wife and I still watch TV together though when we can't find something we both want to watch I'll read a book on my tablet instead of a hardcopy of it.
Militarily we had rockets, jets and missiles and even advanced forms of hand held guns. Remember it was a big deal to have a Colt 1911. That gun has been mimicked all over the world.
So? It's a weapon. Rock, spear, sword, bow, flintlock, M1911A1, death ray, they're all doing the same job for the same reasons. The details are changing, but the core facts are the same. We still need weapons to defend ourselves, our loved ones, and what matters to us from those that would do us harm. We've gotten a bit more sophisticated about it than the ass's jaw Cain used to kill Able but we're still finding ourselves killing each other, the number of moving parts in what we use to do it just keeps going up.
The US wasn't even nearly as developed as it was in 1913. For many places like the mid West it might as well be the Civil War era. Consumerism was still relatively new but growing fast.
And today we've got places in the world that are still at a stone age level of development. What's your point? Consumerism isn't new. Since the dawn of time people have wanted things, things beyond their basic needs. The only real change is that our improved technology has allowed us more leisure time to enjoy those things, and our prosperity has allowed more people to collect more stuff but what about that is changing the basics of how we live?
There are a lot of things that people in 1963 had that people in 1913 would have never thought up.
That's not exactly new. We have no idea what they'll have thought up in 2063. The future being an unknown is a constant.
I don't think you're getting my basic argument. What about human nature and what about how we live has really changed? That's my point. Human life has been relatively static for the last 10,000 years, probably longer. As much as our technology has advanced we are still humans, the same as the ancient Babylonians, living our lives in much the same manner. Creature comforts have increased, we tend to have more free time, but in the end human life is human life. So when you watch sci-fi be suspicious of anything that radically changes how people live.
