The article discusses how decision-making technology needs to consider more than just theoretical techniques. While numerical methods are strong in theory, they only cover a small part of decision-making. Knowledge-based systems offer more flexibility but lack a clear decision theory. The researchers are working on a new approach called argumentation, which involves reasoning for and against decision options using general domain theories. This method has been successful in decision support applications. The challenge now is to develop a comprehensive theory that includes autonomous decision-making, where agents can ask questions and make decisions based on reflection about their goals and beliefs.
