Rebecca MacKinnon is Visiting Fellow at Princeton's Center for Information Technology.

Rebecca's presentation explored two key arguments: first, that China should challenge our assumptions about the inherent relationship between the internet and democratization; and second that existing democracies are currently legislating in ways that may jeopardize the empowering potential of the internet.

The emergence of the internet in China has enabled many people to engage in a more varied public discourse than ever before. The government has also begun to actively engage with its Netizens; for example, Wen Jiabao recently instigated an annual live web chat in which he takes questions on a wide range of social and political issues.

But we should not equate this more open discourse with a move towards democracy, for at least two reasons:

The government still largely controls the conversation: While Wen Jiabao may have been happy to engage in online debate, negative commentary by a prominent blogger (pointing out that this engagement is meaningless the absence of political structures) was swiftly removed. By putting the onus on providers such as blog platforms, China is successfully keeping more controversial content from ever appearing online. Attempts to openly criticize the government or to politically organize are still regularly met with arrest and imprisonment. And the government has adopted a much more sophisticated strategy for media coverage in recent years. Recognizing that press blackouts on controversial events are no longer viable in the age of the camera phone, it now allows these to be reported, saturating the public with its approved version of events, whilst squeezing out individual accounts by citizens.

The government is using the internet to argue that does not need democratic structures to engage its people: Far from signally the death of the Communist Party (as Rebecca and her CNN colleagues had predicted in the 90s), the internet may actually be prolonging its survival because it allows the regime to claim it can engage with its people without political structures. Many educated people in China buy into the idea that they can now be heard, and without a commitment to invest time and resources in circumventing censorship, they remain unaware of some of the most serious abuses. The internet may certainly serve a role in promoting deliberation, but China demonstrates that this deliberation can exist in an authoritarian context.

Meanwhile, in existing democracies, efforts to solve issues related to security and protection are causing governments to legislate in ways that move them closer to illiberal models of surveillance and censorship. In South Korea, the government has instigated a law requiring users of certain sites to create accounts that include their national ID number. This makes it extremely easy for authorities to identify authors who previously could have remained anonymous, and has already led to several arrests. In the UK, the Digital Economy Bill, aimed at preventing copyright infringements, will force ISPs to monitor customers' use of their networks and report suspicious activity to copyright groups. Concerns for child safety online have recently led some UK campaign groups to lend support to China's idea to pre-install all new PCs with censorship software.  These examples highlight the need for a renewed debate about the right balance between security and liberty online. As we come to rely on the internet more and more for understanding the world around us, governments need to think holistically about how their policies will shape its use and impact.

Kentaro Toyama is a visiting scholar at the School of Information at the University of California, Berkeley.  Until 2009, he was assistant managing director of Microsoft Research India, which he co-founded in 2005.

Kentaro identified a number of myths that surround the field of ICT4D and argued that these can confuse our thinking about the proper role for technology in addressing development problems.

Myth 1: Technology x will save the world: The history of writing on technology shows that each new advance tends to be greeted with unbridled enthusiasm about its potential impact. Where once people were convinced television could solve all social and political problems, today we are putting that burden onto mobile phones.

Myth 2: Poor people have no alternatives:  We can often assume that technology is the only way that poor people will be access certain goods. In reality, there are usually non-technological routes to information and services that are free and therefore preferable.

Myth 3: ‘Needs' are more pressing than desires: A high proportion of the income of the very poor goes on what Western observers might view as ‘luxury' items: (music, photos, festivals & weddings) rather than ‘basics' such as healthcare.

Myth 4: ‘Needs' translate into business models: Building a business model around the needs of poor communities is possible, but there are significant barriers. Poor populations are harder to reach, and they may not want to pay for the services you provide, even if their value seems obvious to you.

Myth 5: If you build it, they will come: Spending is not always rational. An eye hospital in India offers extremely high quality cataract operations for free and covers all related costs. 10% of those offered the service will still refuse to have the operation.

Myth 6: ICT undoes the problem of the rich getting richer: In contexts where literacy and social capital are unevenly distributed, technology tends to amplify inequalities rather than reduce them. An email account cannot make you more connected unless you have some existing social network to build on.

Myth 7: Hardware and software are one-time costs: Kentaro estimates that the average One Laptop per Child will in fact cost $250 per child per year to cover breakage, connectivity, power, maintenance and training.

Myth 8: Automated is always cheaper and better: Where labor is cheap and populations are illiterate, automated systems are not necessarily preferable. Greater accuracy may be another reason to favor voice and human mediated systems.

Myth 9: Information is the real bottle-neck:  Those in the ICT4D world are prone to overestimate the significance of information gaps. Even if you connect a farmer to an agricultural expert via a PC, there are a host of other barriers to be overcome before he can actually increase his yields, including: literacy, poor transport links, and a lack of volume buyers for seeds, pesticides etc.

Kentaro contends that when technology makes a difference in development, it is always as much to do with the input of committed and competent individuals and organizations. Despite this, the focus when reporting ICT4D projects quickly slips into extolling the virtues of the technology itself, not the human component. This says much about the seductive quality of technology. Myths about its potential persist because we have a strong desire to see the triumph of clever ideas and ingenuity, and to believe that one time catalytic investments can have such an impact. The reality is always more complex.

The release last week of the Obama administration's Nuclear Posture Review brings long overdue attention to the vital issue of U.S. strategic posture. Issues raised in the NPR and START have reinvigorated a crucial national nuclear dialogue that has been missing.

As the chairman and vice chairman of Congress's bipartisan Strategic Posture Commission, which issued its report last May, we have watched with great interest the administration's steady progress this past year on its Nuclear Posture Review and the START negotiations.

Themes from our report run through the Nuclear Posture Review and are embodied in the new START agreement. While debate and disagreement must be part of the crossfire in this renewed nuclear dialogue, we want to emphasize important dimensions of both the Posture Review and START treaty that figure prominently in our bipartisan report.

Now that the NPR is completed, we see that it is compatible with our recommendations. The review gives a comprehensive and pragmatic plan for reducing nuclear risks to the United States. We believe it offers a bipartisan path forward - while allowing for healthy disagreements on specific issues.

And it incorporates many of our points - such as pursuing a quick and modest reduction of nuclear weapons with Russia and sustaining the nuclear triad of land-based ICBMs, sea-based SLBMs and bombers. It also recognizes that nuclear weapons safeguarded U.S. security during the Cold War by deterring attack and that we will need them for deterrence in the foreseeable future, as long as others also possess them.

We also see that the NPR puts special emphasis, as our report recommended, on improving the nation's complex nuclear infrastructure and enhancing programs to recruit and keep the nation's best scientific minds. The administration's commitment to increase investment in our national laboratories also ensures that they continue their important role in sustaining a safe, secure and effective nuclear arsenal and in solving many other problems facing the nation.

The review is correct to make preventing nuclear terrorism and proliferation the top priority, while also seeking to strengthen deterrence and to reassure U.S. allies and recognizing the importance of strategic stability with Russia and an emerging China. Our commission reached the same conclusions.

The NPR's changes in U.S. declaratory policy - especially the assurance that Washington "will not use or threaten to use nuclear weapons against non-nuclear parties to the Nonproliferation Treaty that are in compliance with their nuclear nonproliferation obligations" - go beyond our recommendation that the U.S. retain "calculated ambiguity."

It is, however, a sensible variation on a theme that the U.S. should support nonproliferation while preserving deterrence for itself and its allies.

We also note that the NPR chose, as we advised, to avoid adopting a "no first use" policy for nuclear weapons while narrowing the scope of possible first use to "extreme circumstances" - language that was in our bipartisan report.

We believe that the substantial edge the U.S. has developed in conventional military capabilities, which the NPR notes, permits this country to sharply reduce reliance on nuclear weapons. But we caution those who make light of this major U.S. strategic advantage and its implications.

We support the NPR's call for the U.S. not to develop new nuclear weapons now. Our report similarly called for a case-by-case approach to extending the life of today's warheads. And we agree that the focus should be on safety, security and reliability - not developing new military capabilities.

The NPR echoes our call to negotiate a worldwide end to the production of new fissile materials - the key ingredients of nuclear weapons.

Our final report strongly endorsed the U.S. deterrence policy to cover our allies and partners with the U.S. nuclear umbrella - an objective the NPR also embraces.

The report suggested deploying proven missile defenses against threats such as North Korea and Iran but emphasized, as the NPR does, that these defenses should not be so big as to encourage Russia to add warheads to counter them, which would only undermine efforts to reduce nuclear weapons. We included China as well as Russia in this.

But in two areas, we believe the NPR might have fallen short of the mark.

First, we understand that the review considered declassifying additional information about the size and composition of the U.S. nuclear stockpile. It should have done so. This would demonstrate U.S. leadership on the transparency that is needed to secure nuclear materials globally and to bolster strategic stability with Russia and China.

Second, the NPR called for the consideration of conventional "prompt global strike" capabilities. But it did not explain whether these systems would have a niche role against small regional powers such as North Korea or be an ultimate substitute for nuclear weapons in deterrence with Russia and China.

We feel the former is the only sensible approach. Keeping this issue ill-defined creates needless anxiety in Moscow and Beijing that could lead to future problems.

Even with these two caveats, the 2010 Nuclear Posture Review makes important strides in charting a sustainable bipartisan path forward for the United States.

Healthy disagreement over some NPR specifics should not obscure the valuable contribution it makes to advancing U.S. security interests - resting, as it does in part, on our bipartisan 2009 Strategic Posture Commission report.
