AI a minefield, could 'lower the barrier to war'

Hollywood fantasy: The reality of AI development is a little more nuanced and a lot less advanced than movies might have us believe. It's the theme of so many dystopian sci-fi books and movies: a super intelligent machine in charge of lethal military hardware becomes self-aware and decides to wreak havoc. But could it actually happen? At the Association for the Advancement of Artificial Intelligence's annual conference in Texas last month, a workshop was held on the ethics of AI development and a panel discussed whether or not so-called'lethal autonomous weapons' should be banned. "There are many arguments, legal, ethical, political and technical for a ban," Toby Walsh, head of the Optimisation Research Group at Australia's research body NICTA and chair of the proceedings, told Fairfax Media.
