There have been two big turning points in human history. The first was the industrial revolution, where machines replaced muscle power. The Second Machine Age is the time when machines are now able to take over a lot of cognitive tasks that humans can do. In this Capgemini interview with Erik Brynjolfsson and Andrew McAfee, authors of the recent book "The Second Machine Age" (www.secondmachineage.com), we get a summary view of what the 2nd Machine Age is, what it means for established companies, and how they should react.
I throughly recommend reading this book. It's an excellent summary of the impact and importance of digital and why it's important for companies to do more.
