In this powerful talk from TEDGlobal, Rebecca MacKinnon describes the expanding struggle for freedom and control in cyberspace, and asks: How do we design the next phase of the Internet with accountability and freedom at its core, rather than control? She believes the internet is headed for a "Magna Carta" moment when citizens around the world demand that their governments protect free speech and their right to connection.

Everything we do is for the purpose of altering consciousness. We form friendships so that we can feel certain emotions, like love, and avoid others, like loneliness. We eat specific foods to enjoy their fleeting presence on our tongues. We read for the pleasure of thinking another person's thoughts. Every waking moment-and even in our dreams-we struggle to direct the flow of sensation, emotion, and cognition toward states of consciousness that we value.Drugs are another means toward this end. Some are illegal; some are stigmatized; some are dangerous-though, perversely, these sets only partially intersect. There are drugs of extraordinary power and utility, like psilocybin (the active compound in "magic mushrooms") and lysergic acid diethylamide (LSD), which pose no apparent risk of addiction and are physically well-tolerated, and yet one can still be sent to prison for their use-while drugs like tobacco and alcohol, which have ruined countless lives, are enjoyed ad libitum in almost every society on earth. There are other points on this continuum-3,4-methylenedioxymethamphetamine (MDMA or "Ecstasy") has remarkable therapeutic potential, but it is also susceptible to abuse, and it appears to be neurotoxic.[1]One of the great responsibilities we have as a society is to educate ourselves, along with the next generation, about which substances are worth ingesting, and for what purpose, and which are not. The problem, however, is that we refer to all biologically active compounds by a single term-"drugs"-and this makes it nearly impossible to have an intelligent discussion about the psychological, medical, ethical, and legal issues surrounding their use. The poverty of our language has been only slightly eased by the introduction of terms like "psychedelics" to differentiate certain visionary compounds, which can produce extraordinary states of ecstasy and insight, from "narcotics" and other classic agents of stupefaction and abuse.

Judging from the skittishness of both markets and "consensus expectations," the United States' economic prospects are confusing. One day, the country is on the brink of a double-dip recession; the next, it is on the verge of a turbo-charged recovery, powered by resilient consumers and US multinationals starting to deploy, at long last, their massive cash reserves. In the process, markets take investors on a wild rollercoaster ride, with the European crisis (riddled with even more confusion and volatility) serving to aggravate their queasiness. This situation is both understandable and increasingly unsettling for America's well-being and that of the global economy. It reflects the impact of fundamental (and historic) economic and financial re-alignments, insufficient policy responses, and system-wide rigidities that frustrate structural change. As a result, there are now legitimate questions about the underlying functioning of the US economy and, therefore, its evolution in the months and years ahead.

Among the demands of the Wall Street protesters is student debt forgiveness - a debt "jubilee." Occupy Philly has a "Student Loan Jubilee Working Group," and other groups are studying the issue. Commentators say debt forgiveness is impossible. Who would foot the bill? But there is one deep pocket that could pull it off - the Federal Reserve. In its first quantitative easing program (QE1), the Fed removed $1.3 trillion in toxic assets from the books of Wall Street banks. For QE4, it could remove $1 trillion in toxic debt from the backs of millions of students.
