Will modern buildings last?

I was driving next to the new courthouse under construction yesterday and noticed they are putting up the facade with the Duval courthouse name etched into it. It got me thinking. One hundred years from now, will these newer buildings (library, fed courthouse, county courthouse, etc) be around like the current historic buildings and stand the test of time? Are downtown buildings today being built to last a century or more if well maintained?

From a totally uneducated point of view, I would say "I hope so". I'm no architect or engineer, but I hear the term "hundred year building" thrown around a lot. Some of the places I've seen built don't look like they'll last 20 years, let alone 100. I get a little nervous when I see huge sheets of styrofoam used anywhere. But I could be wrong.

Take a look at the fate of "modern architecture" in Jacksonville. An awful lot of it has been destroyed within 40 years of its creation. Much of the destruction has been not due to termites or poor construction but to changing tastes.
