Read the following passage and answer the questions based on it:
One of the biggest ethical dilemmas of the twenty-first century is brought up by the integration of artificial intelligence (Al) into modern combat, particularly in the form of autonomous weapons systems (AWS). The promise of strategic advantage is pitted against fundamental ethical principles in the fiercely debated issue of whether or not such “killer robots” should be allowed in combat. Supporters contend that autonomous weapons might decrease the loss of human life, since they do not fear, become tired, or suffer the emotional stress that can cause human mistakes in combat. They also might be able to operate with more accuracy and rapidity in an unpredictable environment, which could decrease civilian casualties.
The ethical arguments are serious, nonetheless. The most compelling argument is the transfer of the life-and-death decision-making from a human to a machine. Opponents contend that a computer, however sophisticated, could never have the moral calculus, compassion, or comprehension of human dignity to make such judgments. This creates an important question of accountability; in the event that an autonomous weapon kills without authorisation, who has the moral and legal culpability? Is it the programmer who wrote the algorithm, the commander who sent the system out, or the state that legitimised its use? The secrecy of Al’s decision-making process, commonly known as a “black box,” also adds to the difficulty in assigning blame. This built-in absence of clear moral and legal norms tests the very foundations of the international laws of armed conflict. Essentially, the debate about autonomous weapons puts us in a position of considering not only the technology but also human responsibility, judgment, and the ethical limits we are prepared to place on the waging of war.
