Social networking technology didn't really exist until 2004-2005. I had the idea to use this technology to bridge this gap between a general interest in addressing social issues and the practical action.

I am in the process of trying to decide whether I can make a substantive and productive contribution to the policy-making process. I was always there because I wanted to work on the pressing issues of the day - I'm interested in energy I'm interested in the climate bill and technology policy.

I knew from the beginning that privacy was going to be a huge issue especially with regard to applying Total Information Awareness in counterterrorism. Because if the technology development was successful a logical place to apply it was inside the United States.

IBM's long-standing mantra is 'Think.' What has always made IBM a fascinating and compelling place for me is the passion of the company and its people to apply technology and scientific thinking to major societal issues.

Energy has become a national security issue and as technology continues to improve there will be more debates like the one on Keystone.

Protein engineering is a technology of molecular machines - of molecular machines that are part of replicators - and so it comes from an area that already raises some of the issues that nanotechnology will raise.

And like I say I think we've got other cases other than Iraq. I do not think the problem of global proliferation of weapons technology of mass destruction is going to go away and that's why I think it is an urgent issue.

I absolutely believe that a lot of the issues raised in 'Amped' about technology migrating into our bodies are issues that we're really going to deal with soon.

We shouldn't build a technology to colour or grey out what people say. The media in general is balanced although there are a lot of issues to be addressed that the media rightly pick up on.

I believe that we were not as effective in the second term dealing with this issue of nuclear none proliferation as we had been during the first term when we stripped Libya and Iraq and A.Q. Khan and their capacity to proliferate nuclear technology.
