Ten thousand years ago, give or take a millennium, Native Americans were recording data on rock which you can still access in the American Southwest. Not as handy perhaps as the Library of Congress or the British Museum where Hi.co will be stored away, but it’s still there for all to see. It is entirely possible that ten thousand years from now, in an unimaginable future, the mountain goat inscribed on this rock wall, will still be moving from darkness into light. Will the Library of Congress still exist? I’m not taking bets either way.
