I believe that given the time he has written this in, Simon Singh has done an excellent job of predicting how the upturn of technology would shift our society and our world towards one of automatic work and technical organization.
It turns out that Singh largely underestimated the rate at which all of this would develop. Technology raced through a lot of the aspects Singh talked about and has moved on to greater things. While we haven't reached certain aspects that Singh explicitly talks about, such as online voting, the Internet has been used to expand our knowledge as well as our capabilities of running and existing in society. Today, we largely consider technology and the Internet to have taken over the world we know today. Although whether it was better or for worse is up in the air for discussion, we can all agree that it has made a sizable impact on who we are as human beings and what we prioritize. That being said, with so much accessible to us in recent days, strong encryption becomes even more critical in regards to our own security as well as the security for everyone else at large. Keeping what we want private as secure as we can make it keeps our mindset and morale high and positive, while being as secure as possible.
