Have you ever watched a History channel show about the lead up to X conflict, or Y situation? Did you find yourself yelling "Wake up, Sheeple™! Don't you see what's coming?!" at the teevee? If so, you should keep in mind that all the key events have been distilled out, and placed in a nice neat line of dominoes in the interest of focus and brevity.
Imagine watching one of those shows that was 30 years long, where each ominous event is noted in under 10 words as it passes on a news ticker at the bottom of the screen, while the main screen shows Charlie Sheen's rants or the new awards show or some wayward starlet's mug shot, or if those things don't strike your fancy, the latest footage from Afghanistan or the recent sports game or the newest tech gadget.
Are your progeny going to say, "Grandpa, we just learned about the global collapse in school, and we couldn't understand why you didn't see it coming." To which you may reply, "Well, little Jenny, it was a different time then. We wanted to keep track of the important things, but other things kept getting in the way. There was the NFL strike, Lindsay Lohan's rehab, decades of baseball stats, arguing on internet forums, video games, the new season of Dexter, iPods, health scares, new electronics, funny cat pictures, internet videos of people hurting themselves, Facebook, new and exciting things that were going to kill us in new and exciting ways, and the pills. So many pills. Have I told you about the pills? Pills for happy, pills for sad. Pills for bored, pills for mad. Pills to treat every affliction, and pills to curb our pill addiction. We had a cure for society's ills, and it was always pills, pills, pills." "Mom! Grandpa's Cat-in-the-Hatting again!"
History is a very interesting thing. Once it's past, we like to comment on it from the comfort of our armchairs. But we refuse to recognize that we're making (or not making!) history every day, and that one day, people in armchairs will look on our history as we looked on our forerunners', and they will comment. What will their comments be?
