This lecture introduces the concept of ethics in artificial intelligence (AI) and its implications for engineers. The instructor outlines the importance of ethical considerations in the development and use of AI technologies. The discussion begins with a definition of ethics as a systematic analysis of values that guide choices and decisions in specific contexts. The instructor emphasizes that technology is not neutral and that ethical considerations are inherent in engineering practices. The lecture also highlights the need for a clear definition of AI, which is crucial for regulatory purposes, particularly in the context of the European Union's AI Act. The instructor proposes a working definition of AI as tools based on algorithms that achieve objectives through statistical and mathematical operations. The lecture sets the stage for further exploration of ethical questions related to AI, particularly in human resources applications, and outlines the structure for upcoming discussions on ethical technology, social justice, and narratives surrounding technological issues.
