Back in '93 and '94, AT&T released a series of "You Will" ads touting the future. For fun, watch them all in this compilation and see how accurate they were.
Some of this they nailed. I attend meetings all week long in my bare feet with people on the other side of the Atlantic Ocean. Some of this we've long surpassed. We're not video talking at a phone booth or buying concert tickets and renewing our driver's license at a kiosk, we're doing it all from our computers and smartphones from just about anywhere in the world.
We're not quite there with a few of these predictions. I can't buy groceries that way, although I can scan my own items. I also believe Canada is lagging behind on that whole "medical history in your pocket" concept. And opening your door with the sound of your voice? That just sounds dangerous.
