Every AI agent we build carries ethical responsibilities. We have to consider how it might impact people's privacy, whether its decisions are fair, and if it could be used for harmful purposes. For example, if an AI agent helps decide who gets a loan or a job, we need to make sure it doesn't unfairly favor or discriminate against certain groups of people. Designing AI agents ethically means being transparent about how they work, preventing bias in the data they learn from, and ensuring human oversight. It's about building technology that helps society rather than harming it, and thinking ahead about potential unintended consequences.
