If anyone wants to read a VERY interesting book about the future of technology, pick up The Singularity Is Near - by Ray Kurzweil.
It is an amazing book that talks about the up and coming innovations in technology, and how it is going to change society. Imagine having tiny robots floating in your bloodstream that allow you to get 100 times more oxygen to your brain and muscles. Imagine tiny robots that will fight disease from inside of your body. Imagine computers that not only "think", but that can intelligently design other computer programs.
It's an amazing book.
