I just read and enjoyed this:
The Future Book was meant to be interactive, moving, alive. Its pages were supposed to be lush with whirling doodads, responsive, hands-on. The old paperback Zork choose-your-own-adventures were just the start. The Future Book would change depending on where you were, how you were feeling. It would incorporate your very environment into its story—the name of the coffee shop you were sitting at, your best friend’s birthday. It would be sly, maybe a little creepy. Definitely programmable. Ulysses would extend indefinitely in any direction you wanted to explore; just tap and some unique, mega-mind-blowing sui generis path of Joycean machine-learned words would wend itself out before your very eyes.
