Mind-expanding topics this week. The threads start with a potentially morbid, but definitely intriguing, topic: what is to become of our personal digital legacies? If that isn’t enough to blow your mind, the next topic is an accounting of the amount of information processed in 2008. Still hanging in there? Then think about what could become of the book if we take advantage of its digital nature. You might not have much room to think big thoughts after those threads, but if you do the last one explores what could become of how our machines talk to each other.
