My Great-grandpa was the same. He was born in 1868, eight years old when Custer got killed, eighteen when Geronomo was raising hell in Arizona, Saw the invention of movies, Tanks, planes, radio, telephone, block long computers, automobiles, Hiroshima and Nagasaki lit up, then died the year the B-52 bomber was accepted for service.
I still remember him and the B-52 is still in service.
I think that people who were born near the turn of the 20th century saw much more paradigm-shifting technological change than those who came afterwards.
In our time, we've mostly witnessed the refinement of technologies that were born in earlier eras. There's no doubt that we've seen a lot of new and amazing things come into being in our lifetimes, but how many of them are truly paradigm-shifting? I'd say, not many. Today, it's the tweaks, improvements, and new applications that move us forward.
