But then again, my parents and grandparents listened to a ventriloquist on the radio ...
Next you'll tell us they had to watch their black and white TVs by candle light :P
I think the most alarming change I have lived through has been being able to order an item internationally and have it show up on my doorstep within a few days.
Depending on the post, I can watch its epic journey as it goes back and forth, like why did that package start out in Kentucky, then go all the way to Guam to come back to me in Georgia?
The things we use the internet for in this regard have expanded so much, every time I get a package from Amazon I joke, "Praise be to Overlord Bezos."
Other than that, tapes to discs to digital drives.
We have so many things on demand. Fruit from the tropics at all times of year, a whole world away.
We went from bringing road atlases with us on trips to google maps to GPS.
The depth of our world blows my mind. I've been spelunking in total darkness, save for head lamp, and then that same day I traveled to another city to the top of a skyscraper and talked with someone on another continent an ocean away.
It's hard to believe the two situations exist on the same world for the same person. I get this sort of mental whiplash a lot, these days.
My Dad describes it too. He was born in 1949, and he often goes on about not growing up with a TV, growing up listening to the radio. Going from Black and White to color. The end of segregation, though he never mentions the moon landing.
He makes fun of the time his Army command got a bunch of computers and put them to work typing out their work instead of writing it out by hand or on typewriters. He fondly recalls the entire computer lab getting fried by a massive thunderstorm caused electric surge.
Up into the modern day. His civilian job at Lockheed. His problems with the ever increasing modernity of computers.
Humanity's sure been on a wild ride.
