But while doing that I'd been following a variety of fields in science and technology, including the work in molecular biology, genetic engineering, and so forth.

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.

I think every student needs access to technology, and I think technology can be a hugely important vehicle to help level the playing field.

Growing up, I wish that I'd had the supplies and laptops and all the new technology that's out right now.

Through all aspects of society be it art, design, the financial markets, government, technology or communications we are witnessing unprecedented global transformation - the result of which is impossible to predict.
