The Download: AI in warfare, and US climate policies

In recent years, intelligent autonomous weapons--weapons that can select and fire upon targets without any human input--have become a matter of serious concern. Giving an AI system the power to decide matters of life and death would radically change warfare forever. But intelligent autonomous weapons that fully displace human decision-making have (likely) yet to see real-world use. Even the "autonomous" drones and ships fielded by the US and other powers are used under close human supervision. However, these systems have become sophisticated enough to raise novel questions--ones that are trickier to answer than the well-covered wrangles over killer robots.
