When my grandmother was a little girl, radio was cutting-edge technology, and so were aircraft.
Thirty years ago, I used a cell phone for the first time. It was about the size (and not much lighter than) a brick. During that same time, I was spending $22 per minute to call my wife from overseas. And the internet didn’t yet exist for the general public. Instead, we used bulletin boards.
Today, all that’s ridiculous.
We can’t know what’s around the corner, but the pace of technological change is arcing ever more towards the vertical…and if the Musks and Bransons of the world are any indication, the “money people” are seeing lots of opportunity Out There, too. And if anyone’s able to invent an FTL drive, watch out — every major corporation on the planet will be eager to be in on it at the ground floor.
