Business strategist Larry Downes, author of Unleashing the Killer App, is much more specificthan most authors about how digital technologies are changing the world – and why technology will advance even more and have more impact. While he addresses numerous issues that have received lots of attention already, Downes also looks beyond the headlines and the obvious implications of digital technology to examine the root causes of change. He pays informed attention to the law and legal structures. He also draws parallels between the digital revolution and the social changes wrought by other technologies, showing how such change ripples through the economy. He presents his findings as nine “laws of disruption,” which, somewhat confusingly, are the change agents of the “Law of Disruption.” This forward-looking book is fun, lively and useful.
