Here is great piece from John J. McKay's blog revisiting the 1962 World's Fair:
Fifty years ago, Seattle was the host of the Century 21 World Exposition, better known simply as the Seattle World's Fair. Century 21 was one of those quaint imperial propaganda exercises during which one of the Great Powers tried to dazzle the rest of the world with its technology and vision of the future. When Dad loaded Mom, my sisters, and me into our 1957 Volkswagon Microbus to go to the World's Fair, I didn't care about any of that; all I knew was that John Glenn's space capsule was there and that I was going to see it.
Unless your name is Jules Verne, predicting the future is a thankless business. Prognosticators almost always expect too much in the short term and not enough in the long term. Whatever else they get right, they never, ever manage to see what's happening to social and cultural mores. Again, like most of these imperial exercises, the Seattle World's Fair depended on its sponsors--civic boosters, corporations, and the government--to create its vision of the future. They made a conscious decision to ignore the people who had spent the most time thinking about the future, science fiction writers. Robert A. Heinlein and Isaac Asimov were both approached to pitch projects for the fair and both were rejected. Not that they would have done a lot better; despite Bob's most earnest hopes, hot young women still do not cluster around smart guys to form polygamous communities.
Still, the Fair boosters and magazine writers of 1962 did their best at envisioning The Future. It's only fair (get it?) that The Future send back a score card.
This is The Future speaking. You spent a lot of time thinking about me lately. I'm touched. Let me tell you what's happened:
We never got jet packs, flying cars, or a four day work week.
Most women have jobs outside the home and they wear pants.
The Cold War ended without a Third World War. Our side won.
Monorails never caught on.
The president is a black man named Barak Hussein Obama. The governor of Louisiana is an East Indian man named Piyush Jindal.
Rock and Roll is still not dead.
You know that disposable future you looked forward to? You know, never wash you clothes. They're paper! Throw them away when they get dirty! Don't wash your dishes. Throw them away and use cheap, attractive, disposable dishes! Ever wonder where all that disposable stuff goes?

The tallest building in the world is in Arabia in a country you've never heard of.
