Are There Any Armies That Are Attesting Swarms?

What if a despotic leader could programme a swarm of drones to kill a set of identified targets with just the push of a button? Due to ever expanding AI capabilities this extreme dystopian vision may not be technically unfeasible. In this second of a four part series responding to this year's BBC Reith lectures from Stuart Russell, Adam Rutherford and Hannah Fry unpick the role of AI in warfare.

Joining them to help them navigate the battlefield of information is Ulrike Franke, a senior policy fellow at the European Council on Foreign Relations who specialises in the future of warfare.

Together they will be investigating 'lethal autonomous weapons' - these are weapons that can find, chose and kill human targets without human supervision. We will be discussing how advanced this technology actually is - some think the world may have already experienced the first ever autonomous strike in Libya. What are the repercussions of this technology for safety on the battlefield , and what are the wider geo-political ramifications?

Stuart Russell has deep concerns over the development of these types of weapons and Rutherford and Fry pick apart some of the ethical debates this technology raises. Who would be responsible if a system malfunctioned and killed a civilian? What's to stop it getting into the wrong hands? Should we even be creating these weapons in the first place - do we instead need a convention banning them? And is that even possible?
