An agent can perform various roles depending on the field in which they operate. In business, agents often act as intermediaries who represent clients in deals and contracts. In espionage, an agent might engage in intelligence gathering, subversive activities, or even sabotage. With the rise of digital and online services, the concept of an agent has expanded to include software agents and AI agents, which function as virtual assistants or representatives in digital spaces.
Throughout history, agents have played critical roles in shaping business deals, international relations, and security efforts. Their influence extends far beyond the traditional view of an agent as a simple representative, having evolved into figures of considerable power and influence in modern society.
