We live at a time when billions have access to unbelievably powerful technology. The most extraordinary tool that has been invented in the last century, the smartphone, is forcing radical changes in the way we live and work - and unlike previous technologies it is in the hands of just about everyone. Coupled with the rise of social media, this has ushered in a new era of deeply personal technology, where individuals now have the ability to work, create and communicate on their own terms. At least that is the optimistic view.

Always On takes readers on an entertaining ride through this turbulent era. It immerses the reader in the most important story of our times - the dramatic impact of hyperconnectivity, the smartphone and social media on everything from our democracy to our employment and our health.
