Hawking's thoughts and advice for the future. This is a great tribute, composed of his speeches, interviews, essays, and previous books. Some passages were recognized from “The Universe in a Nutshell”. Glad to find his humor still made the cut.

He explains ideas in an understandable way, using metaphors like bags of sugar and bank overdrafts to explain quantum mechanics. I only got hopelessly lost a few times. The brief answers to these big questions are pretty big: how we popped into existence, modifying our DNA to survive, how long civilization has left, and the remaining potential for time travel and warp travel were fascinating. Hawking’s nonpartisan advice on the planet is something I want to find more of.

The afterword by his daughter is excellent.
