Straight off: This is a great book! Mr. Russell writes intelligently and intelligably about where we've been, where we're probably headed and gives us some optimistic views on where some of the choices might lead us, if "we" are thoughtful about "our" choices.

This book presents some incredibly complex themes, and even delivers physics, understandably! The hallmark of any great writer, in my view, is to make himself or herself understood to the vast majority of people. Mr. Russell has accomplished that quite admirably. This is the best book on futuristic thinking I've ever read. Reading this book felt like having a conversation with this writer. A pure pleasure! And, a must read for any thoughtful person.
