Now that's a funny image: I'm imagining a time-traveller coming back from the future where Google has created Skynet, and telling Apple "if you create a social network in 2010—don't worry, you can shut it down a year later—you'll scare Google into pushing their own social network out the door, it'll infect their tech culture utterly, and you'll gain a five-year lead on anything you want to put out from them on. (Also, the timeline will be saved.)"
