Description: Lethality in the context of artificial intelligence (AI) refers to the potential of AI systems to cause harm, especially in military or security situations. This concept encompasses not only the ability of a system to execute actions that result in physical harm but also the ethical and moral implications of its use. Lethality can manifest in various forms, from autonomous weapon systems that make decisions about the use of force without human intervention to algorithms that can influence critical decisions in crisis situations. Lethality in AI raises fundamental questions about responsibility, decision-making, and human control over technologies that can act autonomously. As technology advances, the line between defensive and offensive use of AI becomes increasingly blurred, generating intense debate about the regulation and ethical development of these technologies. Lethality also extends to other fields, where the use of AI can have significant consequences for public health and biological security. In summary, lethality in AI is a complex topic that involves technical, ethical, and social considerations, and understanding it is crucial for the responsible development of technology.
