A New York World's Fair in 2014?

It's interesting to see a mayoral candidate in New York talking about that city hosting a world's fair again, but 2014 is WAY too soon, but it would be great to see another city interested in 2022 or 2025.

Typically, in articles like these, comments run along typical lines. There are usually two points people try to make:

1. World's fairs don't happen anymore (or "They still have world's fairs?")

2. We don't need world's fairs anymore because we know all about other countries.

In working out my usual "talking points" about why we need world's fairs, it occurs to me that those two sentiments negate each other. Clearly, Americans don't REALLY know what's going on in the rest of the world, at least not in countries that we aren't at war with.
