Which century saw the biggest change?

My peepaw was born in 1888.
He passed in 1975.

Reconstruction & horses to putting a man on the moon and TV.

That’s a pretty big change.

Change is constantly accelerating so 1919-2019.

Someone over a hundred years old saw the span of horse and buggy to assembly line of the model T all the way to self driving cars starting. They basically got to see the whole history of humans driving cars which will end in the not to distant future.

What will people say about us in 70-80 years? Some of us were around before the internet and cell phones. I’m guess people will look back and think that the internet and wireless communication is at least as big of a world changer as the automobile and airplane.

I say the 21st even though we are just 19 years into it. Earlier generations anticipated things like flight and space travel, so while they were big advancements they were not revolutionary. My grandparents never could have conceived of two men being married or the gender fluidity foolishness being framed down our throats today.
