It started with a simple filter. Fred sent email from his bank to a Banking folder.
Then, Fred filtered some mailing lists into their own folders.
All the while, Fred was creating filters for Spam, sending it to the trash.
A few rules here, a few filters there.
Then Fred added auto-responders. This let people know he got their mail.
Pretty soon, Fred’s email box could run itself.
Fred’s car, on the other hand, couldn’t drive itself.
He got drunk and ran into a tree, and died.
But Fred’s email box kept on going.
And so will yours, one day.
