After all, when I was very little, we had automobiles, airlines, radio, television, electricity, refrigerators, air conditioners, etc.
In your average neighborhood and home you pretty much have all the same things, or things that look similar.
For example, although we now have microwave ovens, they are still a box you cook things in, similar to the toaster oven of decades ago.
Our TV’s are bigger and recently went high-def, but they still fill the same role of the older CRT TV boxes.
The appearance of everyday life hasn't changed that much over my lifetime, as compared to the changes my grandfather must have witnessed.
What he witnessed was likely similar to the changes witnessed by people now in Third World countries who thirty or forty years ago were walking behind water buffalo plowing fields, but today are answering technical support phones.
Solid state electronics, with the miniaturization of electronic circuits and the advent of the computer rather than mechanical means of calculation.
Spinoffs include the hand calculator, electronic watches, cell phones, the home computer, computer systems in cars including navigational systems which rely on satellite technology.
With all this comes the ability to track shipments of materials globally in real time, to maintain inventory, track sales/usage, and to even farm more efficiently by using GPS to guide the application of fertilizer, herbicides, and seed.
Maritime navigation to within a few feet of previous locations (talk about fishing holes, oyster bars, etc.)
We have seen changes we take for granted, but those changes, those culturally pervasive changes aren't always obvious. We take them for granted, but those all occurred in my lifetime as a result of the space race. Right down to severe weather alerts.
(Thumbing my nose at all the people who said we needed to spend the money right here on the planet who line up for free cell phones now).
Medically, those selfsame spinoffs have made it possible to create a 3-D image of a patient's insides and transmit it in a few hours, anywhere in the world.
Progress with vaccines and antibiotics has rendered many the diseases of my youth more an inconvenience than a threat, or eliminated them completely. (Two of the kids I went to school with had had polio.)
Now, families have 2.n children on average, instead of burying that many before they turned ten.
We can travel from coast to coast in a few days instead of weeks, and not have to ride the pullman to get there...or we can fly there in a few hours, all on the same plane (instead of splitting the family up, just in case...), and all expect to arrive fine (if groped by one of the latest developments.)
Nuclear power, including naval reactors which have changed the balance of power in the world, so far, in our favor.
This all hasn't been without its downsides. I also recall when you could fill out the order form and drop a check in with it and have that rifle or handgun come to your house, parcel post. No further paperwork was required).
Now, computerized surveillance of virtually anything someone can think of has made our culture far less private, and more totalitarian. You can only control that which you can keep track of, and so much more can be kept track of. This wouldn't be a problem, to have this capability, if only it was not used to make the walls close in on humanity, but not minding one's own business has become cheaper and more efficient than ever.
I recall getting mercury dimes and buffalo nickels (and the rare indian head penny) in change. The dimes, quarters, and halves were all silver, and if you wanted, you could get silver dollars at the bank--for a dollar. now, thanks to inflation and currency manipulation, along with the ties to intrinsic value, our dollar barely buys what a dime used to .
We produced a lot more of our own oil, back when. (We're using new technologies to try to end that imbalance, ones which did not exist thirty years ago.)
The changes for my grandfather were relatively few. He farmed tobacco, a crop which required manual labor to harvest (and still does), and which was labor intensive when he was a child.
He fished for food and fun, from a wooden skiff, and those still exist, and although outboard motors were nice, he commonly rowed or sculled the skiff, and he could still rig it to drop a sideboard and sail.
The automobile was the major change, and using tractors instead of horses. To my knowledge, he never flew anywhere, and he and my grandmother took a steamboat excursion on their honeymoon. He read National Geographic most of his life.
He had had a television since the late 40s (1947, actually) but only got a couple of channels on it. The transition from black and white to color didn't affect him much, he preferred to read. I do also, but over half of what I read comes via the internet.
The biggest difference is that we expect change. It has become routine.
My grandfathers skeptically accepted it, at least in some technological regards. Underneath it all, human nature remains the same.
