How about the internet? Autumn and I were commenting yesterday afternoon about how quickly and completely it's tied into everything we do, every day. A decade ago, the words Google, Torrent and Facebook were nonsense. Today they're tools to keep me connected to people I'd normally have never seen again, provide me with a wealth of free TV shows, music and movies from around the world, and answer any question I might have in exhaustive detail in nanoseconds. It's really amazing how different the world is today than it was ten or fifteen years ago.
