You used to have all your friends' numbers stored inside your brain forever. Now your smart phone does that for you, and the only number you can recall is your own. And also the number for the DJ Jazzy Jeff & Fresh Prince hotline, for some reason. (1-900-909-JEFF.)
You use to be able to wander around all parts of an airport, even if you didn't have a flight. Which is too bad, because everyone knows the most exciting, least excruciating place to hang out is the airport!
Once a plan was marked down in a planner, it was on. Now, you can put a plan down in your Google calendar...and then just as easily delete it, so it's gone forever and nothing means anything anymore. Hooray for technology!
It used to be a fun prank you might do at a pool party. Today, if you do this, there's a good chance you destroy their smart phone. And if you don't have access to the internet at all times, do you even exist?
You used to watch one episode at a time. And then talk to your friends about the episode as you'd wait a week for the next one. Now you can watch everything at once, then try to talk to your friends about it, except that one friend hasn't watched it all yet and is like, "Hey, no spoilers!" So to be safe, you never discuss the show with anyone. Isn't progress amazing?
