I loved this for its disciplinary perspectives - 167 (and counting) short essays from eminent scientists (physical, biological, social), technologists, designers, editors, authors, makers and artists responding to Edge's World Question Center's 14th annual question, 'How is the internet changing the way you think?' (Yes, 'you').
Themes include the importance of focus, the externalisation of knowledge and memory, autonomy, alienation, and the new importance of social networks.
