In this chapter, political philosopher Alex Leveringhaus asks whether Lethal Autonomous Weapons (AWS) are morally repugnant and whether this entails that they should be prohibited by international law. To this end, Leveringhaus critically surveys three prominent ethical arguments against AWS: firstly, AWS create ‘responsibility gaps’; secondly, that their use is incompatible with human dignity; and ,thirdly, that AWS replace human agency with artificial agency. He argues that some of these arguments fail to show that AWS are morally different from more established weapons. However, the author concludes that AWS are currently problematic due to their lack of predictability.

In this chapter, the philosophers Oliver Mueller and Boris Essmann address AI-supported neurotechnology, especially Brain–Computer Interfaces (BCIs) that may in the future supplement and restore functioning in agency-limited individuals or even augment or enhance capacities for natural agency. The authors propose a normative framework for the evaluation of neurotechnological and AI-assisted agency based on ‘cyberbilities’. These are capabilities that emerge from human–machine interactions in which agency is distributed across human and artificial elements. The authors conclude by providing a list of cyberbilities that is meant to support the well-being of individuals.
