I was reading the December 1916 issue of The Scoop (as one does), a magazine “written by newspaper men for newspaper men,” which is filled with fascinating anecdotes about the way the world was for journalists 100 years ago, when I came across a reminder that the technology we think of as essential often … isn’t.

A full-page ad which appears on the back cover decries the fact Congress appropriated funds for continued mail delivery by pneumatic tubes in New York City, but failed to do the same for Chicago. According to the ad (which is unsigned, so is apparently more of an editorial), there were 10 miles of two-way, eight-inch tubes running under Chicago at the time which delivered 8,000,000 pieces of mail daily.

In response to the idea that mail should instead be delivered by trucks rather than pneumatic tubes, the question is asked, “If we are going backward, why not get a wheelbarrow?”

“Any change,” insists the author of this piece, “would be calamitous.”

Well, here we are, a century later, and that calamity never came.

Which makes me wonder … what technology do we hold dear today, and insist we could not live without, will a century from now seem as quaint as pneumatic tubes do today?
