This document discusses how much artificial intelligence can be trusted. It begins with an introduction that defines artificial intelligence and discusses major techniques like machine learning. It then reviews literature on incidents where AI systems caused harm, like a Tesla crash or a robot killing a Volkswagen employee. The document considers how much AI systems can be trusted given that they are based on algorithms and can have security problems or unintended biases. It concludes that while AI offers benefits, its future is unknown and work is needed to develop trusted algorithms and ensure new technologies are developed safely.
