What will the world of technology look like 30 years from now? Megatech: Technology In 2050 tries to tackle this question. Edited by The Economist's executive editor Daniel Franklin, the book is a collection of essays by eminent personalities like Frank Wilczek, Alastair Reynolds, Nancy Kress and Melinda Gates--each one of whom tells their version of the future. An essay by Luciano Floridi, professor of philosophy and ethics of information at the University of Oxford in the UK, talks about Artificial Intelligence (AI). In "The Ethics Of Artificial Intelligence", he says the threat of monstrous machines dominating humanity is imaginary, but the risk of humanity misusing its machines is real. In an email interview, Prof. Floridi talks about how real, or not, the threat of AI is.
