The other day I drove through Huntsville, Alabama. Beside the freeway is the Space and Rocket Center, and I could easily see the Saturn V, other earlier rockets, and Space Shuttle on display there.
I thought, "It's like driving past the Victoria."
We think of our civilisation as old and beat down sometimes. But if we survive, a thousand years from now those things will be like Gutenberg's first printing press, Leeuwenhoek's microscope, or Euclid's pen. Art, technology, desire, purity, compromise, all the things that make us us.
Think about it- when you start naming people who lived more than five centuries ago, who are they? Explorers- mathematicians, travelers, artists.
From the century we were born in, Goddard might be the remembered name when Obama and Hitler are obscure Wikipedia entries.
We are just getting started.
