This book is formalizing perfectly my thoughts for the future of mankind: How to better link humans through technology, specifically mind to mind technology. It was a fascinating account of how we might interface brains between them, using existing technologies (that still needs to be much improved upon).
The book was also telling the personal story of its author, how he found meaning, how he discovered the power of touch, of real human contact, and how he found love. This might seem completely how of place for such a book, but it is not. On the contrary, he knew we could accuse him of wanting to replace humans by a mindless zombies dystopia like the Borg in Star Trek. So the author used his personal experiences to stress the importance of rediscovering human relations and sense of community. To illustrate how a technology that would allow humans to share emotion over the internet might be more humanizing that current communication systems.
The book imagined how a global self aware consciousness might emerge and what form it could take.
In short, this is a very inspiring book. I hope it encouraged entrepreneurs to explore the possibilities of brain-computer interface. Certainly I will be paying close attention to the field and help if I can make this dream come true.
