I am not sure if this book portrays a utopian view of the future of mankind or a dystopian one (I err on the side of utopian probably). However what it does is introduce the reader, from one of the best AI minds of our time what the future will look like, as the delineation between man and machine is eroded.
This is a highly recommended read, not strictly digital signage but technology related.
The book is available here
