Yep... I have mused on this many times.

At ónly'73, I remember little tube radios ...and no turn signal on cars. You stuck one arm out the window.
I remember my mother crying at the death of FDR. And my father, who was born in 1907, recalls the first car in his little town of Lost Springs, Kansas.... it was a White Steamer owned by the doctor.

I have a letter from my grandfather to my grandmother in 1901, worrying that he might have trouble getting 20 miles to pick her up in a few days, as it had been raining and it was so muddy that he'd need 6 horses to pull the wagon.

   And very few of the drugs we use now existed when I started school in 1945.

And unbelievable, imaginary technology we chuckled over in the Dick Tracy comic strip..(wrist radios...etc) have been FAR surpassed.
