Mankind is still decades away from self-learning machines that are as intelligent as humans. But already today, chatbots, robots, digital assistants and other artificially intelligent entities exist that can emulate certain human abilities. Scientists and AI experts agree that we are in a race against time: we need to establish ethical guidelines before technology catches up with us. While AI Professor Jürgen Schmidhuber predicts artificial intelligence will be able to control robotic factories in space, the Swedish-American physicist Max Tegmark warns against a totalitarian AI surveillance state, and the philosopher Thomas Metzinger predicts a deadly AI arms race. But Metzinger also believes that Europe in particular can play a pioneering role on the threshold of this new era: creating a binding international code of ethics.
