I subscribe to the notion that ethics is entirely rational and maps to game theory. Ethics is about the principled resolution of conflicts of interest between autonomous agents under conditions of shared purpose when playing long games. [1] With this in mind, it is crucial to model incentives and their consequences for systems to evaluate ethics. On the most general level, we can take the goal of avoiding suffering as the shared purpose of all humans on earth. Additionally, maintaining the global civilization might be another high-level goal. Technologists with the ability to create and change technological systems should do so ethically by considering these goals and projecting the impact of the system they create into the distant future. Making this difficult, the complexity of networks of human and non-human entities interacting through technology on a global scale has become overwhelming. Additionally, technology changes at such a fast pace that national and global elites cannot anticipate its full impact anymore, leading to increasing randomness in societies trajectories without anyone being able to formulate and implement a coherent plan projecting them into the future. Therefore it is even more critical that technologists evaluate the ethics and impacts of their actions, especially given the enormous leverage that computer technology offers.
