Ethics of Autonomous Weapon Systems

Introduction

• Definition and explanation of autonomous weapon systems (AWS).
• Discussion of the ethical arguments for and against AWS.
• Reflection on whether AWS should be banned.

Definition of Autonomous Weapon Systems

• Autonomy: Ability to act or make decisions independently.
• Weak Autonomy: Systems that are capable of acting independently of immediate human control (e.g., fire-and-forget missile systems).
• Strong Autonomy: Systems that select their own targets post-deployment (e.g., fictional killer robots from Terminator).
• Strong autonomy implies decision-making in target selection without human intervention once deployed.

Ethical Concerns and Campaigns

• Campaign to Stop Killer Robots: Advocates for an international treaty to ensure human control over AWS.
• Ethical concerns include destabilization, civilian harm, misuse outside of armed conflict, and accountability gaps.

General Problems with AWS

• Arms Race: AWS could lead to a destabilizing arms race similar to other military technologies.
• Ease of War Initiation: AWS could lower the threshold for going to war.
• Tragic Mistakes: AWS could make unintentional errors with severe consequences.
• Broader Applications: Potential misuse in policing and border control.

Specific Ethical Problems

• Lack of Human Judgment: AWS may lack compassion and judgment required for ethical decisions.
• Accountability Gaps: Unclear who can be held responsible for AWS actions.

Argument Against AWS (Sparrow's Argument)

• Responsibility Gaps: If AWS kills someone wrongfully, no one can be justly held responsible (designers, commanders, or the AWS itself).
• Moral Requirements: It is essential that someone be held responsible for acts during war (respect for enemy and ethical conduct).

Detailed Argument

1. Premise 1: Morally right to deploy AWS only if responsibility can be assigned for wrongful acts.
2. Premises 2-5: Neither designers, commanders, or AWS can be justly held responsible due to autonomy.
3. Conclusion: If no responsibility can be assigned, deploying AWS is morally wrong.

Challenges to Sparrow's Argument

• Premise 4 Challenge: Future AWS could be conscious and capable of suffering, potentially allowing for punishment.
• Premise 3 Challenge: Commanders could be responsible in analogous situations with human soldiers.
• Premise 2 Challenge: Responsibility could be attributed if AWS follows programmed rules.
• Premise 1 Challenge: Perhaps responsibility for deployment suffices for moral rightness.

Argument In Favor of AWS (Arkin's Argument)

• Ethical Performance: Advanced AWS could behave more ethically than human soldiers (no self-preservation instinct, better target identification, no emotional bias).
• Monitoring Capability: Can monitor and report ethical behavior in the battlefield.

Considerations

• Technological Advancement: AWS must be sufficiently advanced to outperform human ethics.
• Initial Deployment Issues: Early AWS likely to be less ethical; improvement process might be costly in terms of human lives.

Conclusion and Reflection

• Debate: Consider both arguments and reflect on whether AWS should be banned.
• Moral Questions: Even if not banned, moral concerns about responsibility gaps and ethical performance exist.
• Future Development: How to design AWS to mitigate ethical problems while advancing technology.
