Economist executive editor Daniel Franklin and expert in the ethics of information Professor Luciano Floridi look at where fast-moving technology will have taken us by 2050 and discuss the new ethical policies we will need to deal with its impact.

How will we be affected by this new world in which brain-computer interfaces, vat-grown cruelty-free meat, knitted cars and guided bullets are all predicted. It is a world that will see vast changes in food production, healthcare, energy production, manufacturing and military balance and one that will have a profound impact on the way we live and work.

Franklin edits the Economist's annual publication The World in... and is editor of a collection of essays Megatech: Technology in 2050. Floridi is a professor of philosophy and ethics of information at the Oxford Internet Institute. He was a contributor to Megatech: Technology in 2050.
