AI could reboot industries and make the economy more productive; it's already infusing many of the products we use daily. But a new report [PDF] by more than 20 researchers from the Universities of Oxford and Cambridge, OpenAI, and the Electronic Frontier Foundation warns that the same technology creates new opportunities for criminals, political operatives, and oppressive governments -- so much so that some AI research may need to be kept secret. From a report: [...] The study is less sure of how to counter such threats. It recommends more research and debate on the risks of AI and suggests that AI researchers need a strong code of ethics. But it also says they should explore ways of restricting potentially dangerous information, in the way that research into other "dual use" technologies with weapons potential is sometimes controlled.
