Does my lifespan count? The internet when I was born vs what we have today today. That was it, every computer and connection. And we could easily go back to 2000 and the difference would still be stunning.

Take my great-grandparents; when they were born (1897) indoor plumbing was a nice thing to have, basically no cars and certainly no powered flight. Well, they died in the 90s. Too long a time slice? 100-years ain't much against human history.
