To my mind, the potential for thousands of people to work together in local and distributed learning communities is very exciting. In a world where news has devolved into grandstanding, badgering, hyperbole, accusation, and sometimes even falsehood, I love the greater public good of intelligent, thoughtful, accurate, reliable content on deep and important subjects — whether algebra, genomics, Buddhist scripture, ethics, cryptography, classical music composition, or parallel programming (to list just a few offerings coming up on the Coursera platform). It is a huge public good when millions and millions of people worldwide want to be more informed, educated, trained, or simply inspired.
