Chuck Klosterman Thinks About the Present As If It Were the Past

Do you ever think about the future? Not tomorrow or next month or post-election, but 100, 200 years in the future.  Everyone alive now will be dead -- and what will be remembered? Which pop stars, movies and books will people still know?  And will people's understanding of gravity change? This is the kind of thing that keeps Chuck Klosterman up at night. He covers all of this (and more) in his new book, "But What If We're Wrong?: Thinking About the Present As If It Were the Past."
