'The rise of the internet, from obscurity to ubiquity in the course of a few decades, has had profound effects on our society and on us as individuals. No one could have predicted how significant it would become, and no one can predict with any certainty how it will develop.
'This is true of the underlying technologies, but it is equally and, arguably more importantly, true of the changes that the internet has on how we communicate and interact with each other. It has brought us an overwhelming range of benefits, providing a universal tool to communicate, to organise our lives and to access entertainment.
'What concerns me most is that this tool brings with it risks that we simply haven't grasped. Social networks encourage us to share every aspect of our lives with our friends, but, by providing that service, those networks see everything that we share, and use that information to categorise, profile and predict us. These services aren't "free" - we pay for them with our personal data, and the profits are huge.' (Guardian article).
