What I learned from this book... a lot of random but really interesting things about how we're pretty much screwed. This book was very funny, but in an informative way, that taught me a lot of different near misses that we've had with technology or events that could have really screwed things up for the world. Also, the chapters about robotics were hilarious. I mean, come on, science, why would you even consider making a robot that can run on human remains? That really is just asking for disaster. So, read this, and then go on cracked.com, and read more things and you will pee your pants because you will be laughing so hard :)
