Why Banning Killer AI Is Easier Said Than Done

As we head deeper into the 21st century, the prospect of getting robots to do the dirty business of killing gets closer with each passing day. In Max Tegmark's new book, Life 3.0: Being Human in the Age of Artificial Intelligence, the MIT physicist and founder of the Future of Life Institute contemplates this seemingly scifi possibility, weighing the potential benefits of autonomous machines in warfare with the tremendous risks. The ultimate challenge, he says, will be convincing world powers to pass on this game-changing technology. AI has the potential to transform virtually every aspect of our existence, but it's not immediately clear if we be able to fully control this awesome power. Radical advances in AI could conceivably result in a utopian paradise, or a techno-hell worthy of a James Cameron movie script.
